TECHNICAL CHARACTERISTICS:

Continuous duty S1:The type of duty is indicated by the symbols S1S9 as defined in standard IEC 60034-1. Duty type S1 refers to operation at aconstant load maintained for sufficient time to allow the machine to reach thermal equilibrium.

Degree of Protection IP55The motors in standard execution heve IP55 degree of protection, where:5 (first number in code):Ingress of dust is not totally prevented but dust does not enter in sufficient quantity to interfere with satisfactory operation ofthe machine.5 (second number in code):Water Protection against the machine from a nozzle from any direction has no harmful effect.

125

IP56 protection can be provided upon request.

Insulation class F:Class F insulation systems are utilised in MarelliMotori motors. This is the most common requirement among the industry today.The class F insulation system allows a temperature rise of 105K, measured by the resistance variation method, and a maximumhot spot temperature value of 155C. The materials and the impregnation systems used make these motors suitable for use intropical environments, for applications with high vibrations and for applications with high thermal variations.

100

Insulation class H can be provided upon request.

Temperature rise compatible with class B:Class B rise allows a maximum winding temperature rise of 80K under normal running conditions (rated voltage, frequency andload) wilh maximum ambient temperature of 40C and altitude below 1000m a.s.l.

Installation 1000m a.s.l.:The performance of standard motors is considered at a maximum altitude of 1000m above sea level (a.s.l.) with motors runningin continuous duty, at nominal voltage and frequency and a maximum ambient temperature of 40C. The table displayed on page30 gives the performance variations of the motors when utilised in other conditions.

BALANCING AND VIBRATION GRADES

The motors are dynamically balance with a half key applied to the shaft extension in accordance with standard IEC 60034-14to vibration severity grade normal (A) in standard execution. The following table indicates the maximum vibration grades withrespect to varying shaft heights.

Large vibrations may occur on motors installed at site, due to various factors such as unsuitable foundations or reaction causedby the driven load. In such cases checks should also be carried out on each element of the installation.

133

Motors can be supplied with a special (B) vibration level on request.

The instrumentation can have a measurement tolerance of 10%.The free suspension condition is achieved by suspending the machine on a spring or by mounting on a elastic support (springs, rubber, etc;)

COUPLING

Elastic or flexible couplings have to be correctly effected in order to avoid the transmission of axial and/or radial loads to themotor shaft and bearings.The permissible radial loads with regards to belt coupling are indicated in the table on page 16.

NOISE

The following table contains the medium values of A-sound pressure level (LpA), measured at a one metre distance accordingto standard ISO R 1680. The sound levels are measured in no-load conditions and have tolerances of 3dB(A). At 60Hz the valuesof sound pressure increase by approximately 4dB(A).

179

To reduce noise levels, a special fan can be fitted to motors from frame size 225 on request.To check possible corresponding deratings, consult Marelli Motori.

11ASI.CT.027.0

BEARINGS

The theoretical lifetime of bearings, L10h according to ISO 281-1 standard, of standard horizontal construction motors, withoutexternal forces (radial and/or axial) is in excess of 50 000 hours. The lifetime of bearings is determined by multiple factors andspecifically by: the lifetime of the grease (mainly on double screen bearings), the environmental conditions and working temperature, the external loads and vibrations.

The motors 132 frame size have double screen prelubricated ball bearings. The correspondent grease life under normaloperating conditions for a motor with horizontal shaft, at 50Hz and maximum ambient temperature of 40C is 10 000 hours in continuous duty for 2-pole motors, 20 000 hours in continuous duty for 24-pole motors.The motors from 160 to 250 frame size have single screen prelabricated ball bearings (without grease nipples).The motors from 280 frame size and above have regreasable bearings (with grease nipples Tecalemit UNI type) and therelative exhausted grease drainage.

The lubrication intervals of motors without grease nipples and the relubrication intervals of motors with gresse nipples areshown in the tables below.The shown values refer to normal operating conditions for a motor horizontally mounted in ambient temperature of 25C.At 40C ambient, the motors need more frequent lubrications and the correspondent greasing intervals will be half of thosegiven in the tables.

138

Motors 160 - 250 frame sizes can be supplied with grease nipples and the relative exhausts grease relief valve on request.

The motors with grease nipples have the type of grease, the quantity and the relubrication interval indicated on the nameplate.

STARTING

The performances of a motor during startings are related to the corresponding feeding voltage by the following relationships:

The starting (or short circuit) current is almost proportional to the feeding voltage: Icc VFeed. The starting torque (Cs) and the maximam torque (CM) of the motor are proportional to the square of the feeding voltage:

Cs V2Feed.

STARTING RESPONSEThe starting current values given in p.u. detailed in the present catalogue allow to calculate the starting current rms values, andso measured after some sinusoidal periods from insertion: in the first instant it is possible to have peek currents which can beup to 2.5 times the stable values. The amplitude of the peeks depends essentially on the instantaneous value of the sinusoidalsupply voltage at the moment of insertion. These peeks are rapidly damped. The starting torque peeks, having an analoguebebaviour, come considerably attenuated by the inertia of the motor and of the coupling load, with negligible resulting stress ofthe shaft and coupling.

TYPE OF STARTINGThe most common starting methods of a three phese induction motor are:

1. Direct-on-line startingStarting by means of direct insertion at the feeding line. In these conditions the starting torque and current values are those givenin the catalogue.

2. Star -Delta startingThis starting method can be adopted in cases where the resistant torque is very low and low starting currents are requested.With this method the leading torque and current, in the starting phase, come reduced by 28% to 30% of the value indicated inthe this catalogue, with a negligible transient at delta insertion.

3. Starting through soft starterThis device supplies a gradually increasing voltage, limiting the starting current and avoiding abrupt insertion. The amplitude ofthe current in the starting phase depends directly on the value of the resistant torque of the coupled load, from the inertia of thesystem and from the pre-set starting times. The device adapts the voltage at the requested torque conditions and allows anenergy saving, particularly with starting at low loads.

4. Starting with autotransformerThe use of an autotransformer permits a reduction of the starting current and also results in a lower leading torque by use ofsimilar relationships;

EXAMPLE OF CALCULATION FOR DIRECTINSERTIONOnce the motor suitable to drive the coupled load has been chosen, the calculation of the starting time in the case of directinsertion can be carried out by applying the following simplified method.

By considering the values in the catalogue for the

starting torque Cs /Cn, the maximum torque Cmax /Cnand the nominal torque Cn, it is possible to obtain themean leading torque by the followIng relationship:

VAT = reduced voltage at exit of autotransformer [V]

IAT = starting current at voltage VAT at the entry of autotransformer [A]

VN = nominal voltage of the motor[V]

IM = starting current at voltage VAT at the entry of motor [A]

I = starting current at nominal voltage [A]

C = starting torque at nominal voltage [Nm]

CAT= starting torque at voltage VAT [Nm]

IM = IVATVN

IAT = I +VATVN

CAT = CVATVN

CM = KCn CS

Cn+ Cmax Cn

25ASI.CT.027.0

The starting time is given by the following relationship:

For heavy starting, where the inertia of the operating machine is greater than 8 times the inertia of the rotor, consult MarelliMotori.

Where:

MOTORS FOR VARIABLE SPEED APPLICATIONS

A.C. motors designed for sinusoidal feeding voltage and constant feeding frequency can, under normal conditions, be used invariable speed applications by means of a frequency converter. Motors for variable speed applications are generally fed by thefrequency converter by upholding the relationship Un/fn up to the speed correspondent to the nominal voltage and frequencyand, for higher speeds, by increasing the frequency and keeping constant the nominal voltage value. The performances of amotor fed by frequency converter depend on the cooling type: self-ventilated motors are suitable for use at loads with quadratictorque/speed shapes (typical case for pumps and fans).

177

When constant torque is required from low speeds, forced ventilation must be employed.

Generally the motor type can be choosen referring to the following diagram by considering: the torque diagram of the motor,the speed range, the cooling type

For motors from 355 to 400 frame size with cooling method IC411 contact MarelliMotori.

In both cases the resistant torque of the driven machine must be lower than the leading torque of the motor for the total runningspeed range.The speed range is set from a minimum frequency FMIM (typically around 5-10Hz depending on the converter), and a maximumfrequency FMAX dictated by the speed limits of the rotating system and/or the reduction in torque.

Motors fed by frequency converter can be subject to voltages between the D-end and N-end bearing arrangements. This is dueto the effects of the feeding system. The values of the aforementioned voltages depend on the characleristios of the frequencyconverter and on the dimensions of the motor itself. For motors from 315 frame size or those where the shaft peak voltageexceeds 500mV, MarelliMotori suggest to insulate one of the bearing arrangments of the motor. Normally this solution is appliedto the N-end of the motor.

These guidelines, coupled with the correct grounding of the operating system, motor and coupled machine, guarantee the bestresults.

178

The use of the converter requires some precautions regarding the voltage peeks and wave-fronts which it transmits to the motorterminals. The values of the aforementioned peeks are dependent on the supply voltage of the frequency converter and it resultsin an amplification relative to the motor feeding cable length.For peak values higher than 1000V at motor terminals and/or for nominal voltages higher than 500V and/or voltage-fronts du/dt> 500V/s at motor terminals, MarelliMotori suggests a reinforced insulation system for the motor and/or the interposition ofappropriate filters between the motor and converter.

VOLTAGE AND FREQUENCY

The European reference voltage recommended in IEC 38 Publication is 230/400V three-phese.The voltages 220/380V and 240/415V of some existing systems will evolve towards the above reference values.The motors described in the table on page 31 are designed to operate under feeding voltage of 230/400V 10% - 50Hz.They are therefore suitable for use on the following supply voltages:- 220/380V 5%- 230/400V 5% e 10%- 240/415V 5%.The motors described in the tables on pages 32-36 have nominal ratings and performances referred to the nominal voltagementioned in the main nameplate, according to the Standard IEC 60034-1. This Standard classifies voltage and frequencyvariations in two different areas A and B as shown in the following figure.

Area A - The motor shall be capable of performing itsprimary funclion continuously, but doesnt need tocomply fully with its performance at rated voltage andfrequency and may exhibit some deviations.

Area B - In this area the motor shall be capable ofperforming its primary function, but may exhibit greaterdeviations from its performance at rated voltage andfrequency than in zone A. Extended operation at theperimeter of zone B is not recommended.
