How do I find the fan I need in this catalog?

If you know the motor manufacturer:

1. Find your motor manufacturer’s listing in the index on the front cover.

2. Turn to the indicated page number and find the column heading “Suggested for Frame No.” in the manufacturer’s data table.

3. Look for the frame size (or sizes) that match your motor’s frame size.

4. Verify that you have selected the correct line item by checking the fan diameter in the “Overall Diameter (D)” data column.

5. After verifying the correct frame size and overall diameter, you can also check “No. of Blades & Material”, “Diameter of Bore,” “Keyway Size,” and, if known, the number of motor “Poles.”

6. The column “Refer to Photo#” gives the photo number from the front pages of the catalog which most closely matches the selected fan.

7. On the left side of the data table, the column “OEM Catalog Number” gives the part number for the manufacturer’s original fan. On the right side of the data table, the column “Jenkins Catalog Number” gives the part number for our cast aluminum replacement fan.

8. If nothing in the manufacturer’s table seems to fit, then give us a call at 1-800-438-3003 or visit our website at for additional fan photos. We can machine one of our stock fans to meet your requirements.

www.jenkins.com

If you DON’T know the motor manufacturer:

1. Find the photo on the front cover which most closely matches the fan you need. Fan series are identified as Series 1 to Series 18.

2. Turn to the page indicated under the photo you have selected. You will see many additional photos for that selected series.

3. Note the photo number which most closely matches the fan you need.

4. From the index on the front cover, find the “Tables” pages for the selected fan series. Notice that the table data is sorted by “Overall Diameter (D),” the 3rd column.

5. Look down the “Overall Diameter (D)” column to find the range of diameter you need. Within this range of diameters, check to see if the photo number noted in step (3) above is shown in the “Refer to Photo #” column 6. If so, then verify the additional dimensional data (columns 7-13) for that fan, determine the bore size you need, and give us a call to order.

6. If the photo number noted in step (3) above does not appear in the range of required diameters, then check the other photo numbers listed under “Refer to Photo#” to see if a close match exists. If not, it may be necessary to return to step (1) above and select a different fan series.

7. If nothing from the Blank Bore Fan Series seems to fit, then give us a call at 1-800-438-3003 or visit our website at www.jenkins.com for additional fan photos. We can machine one of our stock fans to meet your requirements.

First, obtain as much of the following data as possible: Fan Diameter, Bore/Shaft Size, Keyway Size, Fan Material (metal/plastic), Motor Manufacturer, Frame Size, RPM, and Fan Part Number. Then ...

FAN APPLICATIONS & SUGGESTIONS

DIMENSIONS: Overall diameter (D) is most critical in determining air delivery over the motor. Blades width (A) is also important, but the number of blades is not significant. Be sure the fan blade you choose clears the bearing housing OD, and the fan cover ID. All catalog dimensions are given in inches. Tolerances are +/- 1/8” on all dimensions except bore.

BORE: We will bore any of our aluminum fans to +/- 0.001” tolerance (straight bore only). We recommend that you order your fan to the same micrometer measurement as the motor shaft journal. To install or remove the fan, warm it with a torch or in an oven, and slip it on the shaft. Please specify keyway size if desired. We do not recommend split hubs in aluminum fans. The split concentrates the stress on the fan back plate, and will encourage cracking failure unless the bore of the fan is within a few thousandths of the shaft size. A “Maximum Allowed Bore” is shown for each bore fan. Large bores may weaken the hub, particularly if a keyway is required. Our Machine Department meets the Calibration Systems Requirements in MIL-STD-45662A.

MATERIAL: Aluminum (Al), Plastic (Pl), and Steel (St) fans are stocked. We will cast special aluminum, brass, and cast iron fans to order. We buy our plastic fans from the motor manufacturers, except for the 2-51 slip ring fan, which we manufacture.

Our aluminum castings are not balanced. We cast 356 Prime Alloy, producing a hardness of approximately Rockwell B-60, suitable for use on explosion-proof motors. The plastic fans we stock are not treated for use on explosion-proof motors. We do not recommend attaching balance weights to any plastic fan.

FRAME: The frame shown is for 1200 and 1800 rpm motors, except those marked “TS” which are 3600 rpm motors. Fans shown for “T” frames are safe for use with the same frame number in either “U” frames or old NEMA frames. They are also safe to use with older frames of higher number as long as the rated horsepower is the same or less than the horsepower of the “T” frame listed.

SPECIAL FANS: We have many fans and patterns in stock which are not illustrated or listed. The best method of identification is to send in a sample, (even if it is broken), for us to match. If we do not have a pattern, we can make a metal pattern or have a wooden pattern made for complex shapes. You are charged for our net cost in obtaining the pattern, but we retain the pattern for future use. Our pattern-making charge is $40.00/hour, Net, plus material costs.

FAN COVERS: We can supply General Electric, Lincoln, Louis Allis, Siemens Energy, Toshiba, and some Teco guards from stock. We will be glad to order Reliance, US Electric and Westinghouse shrouds for you. We also make custom fan covers in our Charlotte facility see Page 67 for more information.

FAN SELECTION & APPLICATION:

We are ready to help you with your motor cooling fan needs. When you know what you need, please specify catalog number, quantity, and special machining with your order. To help you choose, our Replacement Motor Fan table lists the name of the original equipment manufacturer (OEM) and shows the manufacturer’s part in our stock. Our suggested Jenkins replacement part is also shown. Choose whichever fan you prefer. For older frames and other brands, we will be happy to check our records to see if we can make a recommendation. However, we strongly rely on your own judgement to be sure a particular fan will fit the enclosure and cause air to flow and cool your motor.

USING THIS CATALOG TO CHOOSE A FAN

HOW TO USE THIS CATALOG TO CHOOSE A FAN BLADE FROM AN UNKNOWN SAMPLE

The tables on pages 27-50 show the fan blades we cast in aluminum that can be machine to your specifications. (Table B2 on page 5 lists our charges to machine a fan blade). We catalog several types of blades. Most motor fans blow air out from the hub (radial air flow), and require a fan cover to direct the air flowing along the motor frame. These radial fans are listed in the tables as Series 1 through Series 7.

SAMPLE OF TABLE FOR BLANK ALUMINUM FAN BLADES

“LINE#” refers to the line number that the fan information is located on. This is used for reference only.“NEW” a dot in the this column means this fan casting has not been listed in a previous Jenkins Fan Catalog.“Overall Diameter (D)” this is the overall or complete outside diameter of the fan casting.“Our Fan Catalog Number” is the Jenkins Electric fan casting part number without machining.“List Price $” refers to the casting selling price before it is bored or otherwise machined. The discount schedule is listed separately.“Refer to Photo #” 161 means that the fan looks like Photo 161. This reference may be an exact likeness, or it may only mean that the fan listed vaguely resembles this photo, and we do not have an accurate photo available. “Blades-Material-Weight” shows the number of blades on the fan, what the fan is made of, and an approximate weight of the fan in pounds. The inch dimensions which follow, (8) “Width of Blades (A)” through (12) “Plate Diameter (H)”, refer to the drawing at the top of each series listing. The width of the blade (A) is an approximate measurement of the blade made to indicate the space needed under the fan cover. The actual blade width may be smaller near the tip.“Maximum Allowed Bore” is the bore which leaves 1/4” hub wall. If a keyway is needed in the wall, the fan bore cannot be this big.“Typical Frame Number” is shown if we know the OEM frame size for this fan.

HOW TO USE THIS CATALOG TO CHOOSE A REPLACEMENT MOTOR FAN, IF YOU HAVE THE MOTOR NAMEPLATE

On pages 51 through 58, we list typical fans used by various OEM’s for their AC and/or DC Motors. We stock fans made by the OEM, and list these in Column (2) for various frame sizes. The OEM fan catalog number begins with a manufacturer initial. The data in the tables refer to the motor manufacturers recommendations for one specific model. Dimensions may vary for other models, so please check your motor shaft and fan OD. Many manufacturers are cutting down fan OD to save power and reduce noise.

“OEM Catalog Number” is the Original Equipment Manufacturer’s fan.“List Price $” refers to the selling price for the OEM part. The discount schedule is listed on 4.“Refer to Photo #” 147 means that this fan looks like Photo 147. This reference may be an exact likeness, or it may only mean that the fan listed vaguely resembles this photo, and we do not have an accurate photo available.“No. of Blades & Materials” shows the number of blades on the fan, and the material of the fan.“Diameter of Bore” refers to size of the hole for mounting the fan on the shaft of the motor.“Keyway Size” refers to size of the key slot for mounting the fan on the shaft of the motor.“Suggested Frame Number” is shown if we know the OEM frame size for this fan.“Poles” is shown if we know the OEM RPM rating for this fan.“Jenkins Catalog Number” is the Jenkins Electric fan casting part number we offer as a replacement for the OEM fan. Our fan replacement may differ in blade number, width, and diameter from the OEM fan. However, in our judgement, our replacement fan will move an equivalent amount of air, and can be mounted on the motor without hitting the frame or cover. (However, you may have to locate it in a slightly different place on the shaft to provide satisfactory mechanical clearances.)“List Price $” refers to the base price for the Jenkins Electric fan casting part number (including all machining). This price is subject to appropiate discounts.

SERIES 2 - PADDLE WHEEL


PHOTO 2022-5 (10-1/8”D) 2B

SERIES 2 FANSSeries 2 fans were originally developed for use on textile-type motors, but many manufacturers use these “paddle-wheel” shapes for both internal and external motor cooling. The absence of a back plate on these fans are particularly adaptable since it is so easy to saw off the blades to reduce the overall diameter or to shape the blade tips.

SERIES 3 FANSSeries 3 fans indicate those fans which have a negligible “E” dimension, i.e., flat-backed fans. Modern, foreign and American motor designs often have squared off or flat end bells, so no recess is required in the fan’s hub area. These fans can be used on many Baldor, GE, Toshiba and other brands. Photo 315 refers to a fan blade used to blow dust, chips, etc. in material handling. These fans are not specifically designed for motor cooling.

SERIES 4 - RECESSED HUB

Refer to Table on Page 34

SERIES 4 FANSSeries 4 fans were first made to resemble General Electric plastic fans with a back clamping, split hub. Other manufacturers have machined the hub on the back to function as a bearing cover, or used a set screw near the back to mount the fan on a short shaft. We added flat-backed fans with equivalent dimensions for GE motors. The front hub is easier to heat and to tighten the set screws. These flat-backed fans are designated 1-001 through 1-103 in Series 1.

SERIES 5 - ARMATURE/ROTOR


SERIES 5 FANSSeries 5 fans are suitable for internal cooling of an AC motor. They have a hub which protrudes from the back plate on the opposite side of the blades. This protruding hub can fit in under the rotor end turns or end ring without interfering with the bearing housings. Photo 501 fans have openings in the back plate to allow air movement through the fan. Photo 502 fans have a solid back plate. Air cannot be moved along the shaft through this type of fan.

SERIES 6 - DEEP RECESS


SERIES 6 FANSSeries 6 fans are those with deep-dished back plate, i.e., Dimension “E” is relatively large. This type is used on many European motors and some old American designs. To change European frame sizes (IEC Numbers) to the approximate NEMA frame, multiply the IEC Number by (1.6). The IEC Frame Number is the motor shaft height (D) in millimeters. The deep hub recess allows the fan to fit around a protruding bearing housing.

SERIES 8 - DIRECTIONAL - AXIAL


SERIES 8 FANSSeries 8 fans are axial flow fans, i.e., they force air to flow along the axis or shaft of the fan blade. All of the previous fans listed are radial flow fans, in that they force air out along the radius of the fan blades, creating a high pressure at the tips. The direction of rotation of a Series 8 is specified by the direction the fan must turn to blow air into the motor. Photo 801 shows a counterclockwise fan and Photo 802 shows a clockwise fan.

Series 1 fans are the type used most often on horizontal TEFC induction motors. These fans have a small hub recess (the “E” dimension in the drawing to the right). The 1-0 through 1-5 were first developed to fit U-Frame General Electric motors and then the patterns were modified slightly to fit other manufacturers’ motors. The 1-30 series were based Reliance Electric fan shapes, and some of the 1-60 fans were added for special Reliance motors. The 1-40 series were based on U.S. Electric blade shapes, The newer General Electric motors have fans like the 1-600 and 1-700 shapes. Many other motors use fans from this table.

Series 2 fans were originally developed for use on textile-type motors, but many manufacturers use these “paddle-wheel” shapes for both internal and external motor cooling. The absence of a back plate on these fans permits air flow through the motor rotor in either direction. These fans are particularly adaptable since it is so easy to saw off the blades to reduce the overall diameter or to shape the blades tips. All fans of this type work by creating a higher pressure at the blade tips. The shape of the fan guard or motor housing then determines the path of the higher pressure air. The pressure is typically a few pounds per square foot near the blade tips and varies with the motor speed.




In 1981 we included our old Series 3 Fans which had a deep dish (large, “E”dimension) with our Series 6 listing. Most of the styles were obsolete. We are now reusing Series 3 to indicate those fans which have a negligible E dimension, i.e., flat-backed fans. Modern foreign and American motor designs often have squared-off or flat end bells, so no recess is required in the fan’s hub area. These fans can be used on many Baldor, GE, Toshiba and other brands. Photo 315 refers to a fan blade used to blow dust, chips, etc. in material handling. These fans are not specifically designed for motor cooling.

Series 4 fans were first made to resemble General Electric plastic fans with a back-clamping, split hub. Other manufacturers have machined the hub on the back to function as a bearing cover, or used a set screw near the back to mount the fan on a short shaft. We added flat-backed fans with equivalent dimensions for GE Motors. The front hub is easier to heat and to tighten the set screws. These flat-backed fans are designated 1-001 through 1-103 in the Series 1 Blank Bore Fan Table.



Series 5 fans are suitable for internal cooling of an AC Motor. They have a hub which protrudes from the back plate on the opposite side to the blades. This protruding hub can fit in under the rotor end turns or end ring without interfering with bearing housings. Photo 501 fans have openings in the back plate to allow air movement through the fan. This allows the fan to draw air through the rotor and then push it toward the stator end turns or out the end bells of the motor. Photo 502 fans have a solid back plate. Air cannot be moved along the shaft, through this type of fan.

Series 6 fans are those with deep-dished back plate, i.e., Dimension “E” is relatively large. This type is used on many European motors and some older American designs. To change European frame sizes (IEC Numbers) to the approximate NEMA frame, multiply the IEC Number by (1.6). The IEC Frame Number is the motor shaft height (D) in millimeters. The deep hub recess allows the fan to fit around a protruding bearing housing. Some of the Series 1 Fans also have a sizable hub recess, so the distinction between them and the Series 6 is not rigorous.

When boring these castings, you should adjust the position of the hub in the lathe chuck to make the blade tips run reasonably true. Irregularities from the casting and grinding processes may mean the hub is not perfectly concentric with the blades.

All of the previous fans listed are radial flow fans, in that they force air out along the radius of the fan blades, creating a high pressure at the tips. The direction of rotation of a Series 8 is specified by the direction the fan must turn to blow air into the motor, when the observer is standing at the shaft end where the fan is mounted. For example, Photo 801 shows a counterclockwise fan. If you rotate that fan CCW on its axis, it will blow air into the page, or away from you. Photo 802 shows a clockwise fan. For CW rotation, the air is forced away from you.

®EZE-SLEEVE®We stock EZE-SLEEVES for our own use in bushing bearing housings in end bells, for bushing bearing

®cartridges, and for bushing shaft holes. The EZE-SLEEVE is made of cast iron with a precision ground OD a few millimeters (mm) greater than the bearing OD, and rough machined ID a few millimeters (mm) less than the

®bearing OD. The first two or three digits of the EZE-SLEEVE catalog number are the bearing OD in millimeters. ®The last two digits of the catalog number are the EZE-SLEEVES length in millimeters. An exact OD is marked

®on each EZE-SLEEVE to the nearest thousandth of an inch, but we recommend that you use your own ®micrometers to verify this dimension. To use an EZE-SLEEVE , bore out the housing to 0.002” smaller than the

precision ground OD. This will provide a 0.002” interference fit. We also suggest you use an anaerobic ®adhesive/sealant to secure the EZE-SLEEVE in place. Finally, finish machine the ID per a standard bearing

® tolerance chart. ABEC-1 fits are shown; precision bearings require a tighter tolerance. EZE-SLEEVE length is greater than the bearing width to allow you to test bore the lip and check it with your micrometers before completing the final cut. This lip will be faced off after the bore is complete. We recommend leaving the bore below the minimum diameter and sanding a few ten-thousandths off the bore to complete the bushing operation.

* Put the number you want printed on the band in this space. for instance AFS-3-6 is a white band for a size 20 lead wire with the number “6” printed on it. We stock the numbers 0 to 9. All are black markings printed on a white PVC flexible sleeves. Letters A through Z and other symbols are available on special orders at an increased price. Colored sleeves are also available at a premium price. We have used these markers on our rewinds, and they stood the varnish and baking cycles satisfactorily. Ask for a sample to try on you own leads. They last better than adhesive number strips, and they are nonconducting.

The 130°C rating allows more load and fewer nuisance trips. The winding temperature is always higher than the thermostat when it trips, so the “Typical Gradients” should be added to the thermostat rating to get the tripping temperature. Modern motors are typically rated to run at 120°C to 130°C winding temperature. Class F allows 155°C winding temperature and U/L allows up to 165°C. The thermostat should trip below these points.
