systems, cement, oil and gas, steel plants, pulp and paper and others.Veritas Quality Institute in accordance with ISO 9001

requirements. As well as all M&C medium and high voltage motors are also certified by internationally recognized certifying

institutions such as CSA (Canada) and CQC (China).

Each parts of the motors mechanical dimension and tolerances comply with GB/T1800~GB/T1804 and ISO standard.Outlineand mounting dimensions and power class of the motors comply with IEC72/JBT10444-2004 standard.These series motors IP

class comply with GB/T4942.1-2001(IP code)-IP55,also customized; These series motors Cooling method comply with

IEC60034-5 standard IC411,and the mounting comply with IEC60034-7(IM code) .

Medium Size 3 Phase AR High Voltage Motor, Slip ring High Voltage Motor, High Voltage AC Motor, HV Motor, slip ring

motor is used to drive Windlass, Press machinery, Crusher, Stock-removing, drawbenchs and other general-purpose machinery.

They can serve as the prime movers in steel, mines, mechanical industries, blower, compressor, transportation, building

materials industry, etc field. The motor has such advantage as high efficiency, energy-saving, low Noise, low vibration, high

start torque, low start current, light weight and reliable performance. They are easy for installation and

maintenance.Comparison of different series High Voltage motors

General

AR large-sized three-phase asynchronous motor (center height 710-1000mm) is the latest products of 90's in our company, its

power degree, installation size and electric performance complies with requirements in the standard IEC, "Quotation and

Performance of Rotating Electric Machine" GB 755 and "Basic Technique Conditions for Large-sized Three-phase

Asynchronous Motor" GB/13957-95. This serial products can substitute the old products designed within "Technique

Conditions for large-sized three-phase asynchronous motor" JB2223-77 and

increase the capacity equal to 10kV motor.

This new serial motor is compact in structure, high in efficiency, excellent in insulation performance and easy in installation

and maintenance, rated frequency is 50HZ, F class insulation. The type of installation is horizontal with foot (IMB3), S1

continues in work type, 6000V or 10000V rated voltage.The AR motor is suitable for various commonly used machine such as : compressor, water pump, breaker, stock-removing

machine and transport plane.The special-purpose motor should be contacted with manufactory before ordering such as:

transmission, blowing machine, coal grinding machine, hoist engine and rolling mill. It is

necessary to reach a technical agreements in adopting special design for ensuring on the

reliable running of electric machine .

Application

Slip Ring Motors

Slip ring motors are usually applied on high inertia loads or

on high resistant starting torque loads. They are also required

when there is starting current limitations on the power supply

system.The most common loads driven by these motors are:

ball mills, crushers, fans, exhausters, shredders and grindersfor cement and mining industries, steel plants, among

others.Slip ring motors can be supplied with motorized

brush-holder system or fixed brush-holder system, as required

by the load and operating conditions.Slip ring motors fitted

with motorized brush-holder system offer important

advantages in terms of maintenance once

they allow the brushes to be in contact with rings only during

motor starting. Hence, avoiding brushes and slip rings wear.

Constructive Characteristics

Frame

Manufactured either with welded steel plates or cast iron, the frame is motor structural component that accommodates, supports

and protects the active magnetic part of the motor. Its rugged construction offers excellent mechanical strengthen to the motor

along with low vibration levels.

Stator

Regarded as the static magnetic part of the motor, the stator consists of a steel laminated core. The coils forming the stator

winding are fitted into the lamination core slots. The stator core is mounted directly on the motor frame.

Winding

The winding is specially designed and specified for the voltage and application they are intended for. Medium and high voltage

motor coils are manufactured with rectangular copper wire, form-coiled and totally mica tape insulated. Conductive and

semi-conductive tapes are also used to insulate the coils to ensure improved resistance to corona effect.

Rotor

Regarded as the rotating component in the electric motor, the rotor consists basically of a shaft and a steel lamination core. On

slip ring motors, either the squirrel cage or the rotor coils are fitted into the lamination core slots. The squirrel cage can be built

with aluminum die cast or with copper or brass.The rotor is designed taking into consideration the required starting torque and

motor operating conditions.Shaft is manufactured with several types of thermally treated steel such as AISI/SAE 1045, 1524.

Balance

M&C counts on a series of equipment to perform balance up to 3600rpm. Computerized equipment allow accurate balance on

all rotors. As a consequence, M&C motors present significantly reduced noise levels. The standard balance is provided in two

planes. However, the company has the capability of providing three plane balancing whenever required or when requested by

the customer.

to be included.

Standard Accessories

- Temperature detectors - PT-100 in the stator winding

- Temperature detectors - PT-100 in the bearings

- Space heaters

- Shaft grounding brushes for VFD applications, or all motors in frame size 450 and larger.

Testing

All M&C motors are tested in accordance with IEC 6034-1 Standards, NEMA MG1 and IEEE 112. With testing capacity for

medium and high voltage motors up to 10,000kVA and voltages up to 15,000V, the M&C testing laboratory is computer

monitored and controlled for extreme accuracy.Tests are divided in three groups: routine, type and special tests.Routine tests are

performed on all motors produced. Besides routine tests, type and special are usually performed on one jiece in a batch of

identical machines or under customer request.

Routine Tests

-Resistance measurement at cold

-No_load test-Locked rotor test

-Hi-pot test

-Insulation resistance test

Type Tests

-All routine tests

-Vibration measurement at cold

-Breakdown test

-Temperature rise test

-Load test at constant voltage

Special Tests
