Special Motors

Bharat Bijlee Ltd manufacturers a wide range of non-standard or special motors which are used various application viz. Torque Motors, Low Vibration Motors, Loco Auxillary Motors and Blowers. A brief about Locomotive Motorthese motors is as below: -

Torque Motors

BBL manufactures TEFC three phase Torque motors. The torque of

these motors is maximum at starting and it has almost linear torque

speed characteristics with zero torque at synchronous speed.

These motors are used in many special applications e.g. Roller

Table motors, High speed tapping machines, clamping devices, etc.

Low Vibration Motors

BBL manufactures Low vibration motors for the machine tool industry. These motors are offered with vibration level up to Precision class C (0.28 mm/sec) or (5 microns peak to peak).

Loco Auxiliary Motors and Blowers

VMT Blowers

BBL manufactures special Auxiliary motors and blowers for the Locomotives

of the Indian railways. The motors are suitable for operation on a supply with

5% Unbalance in the three phases and with voltage variation from 290 V to

500 V. BBL supplies motors for the following equipment used on the loco.

Compressor (1000 LPM as well as 2000 LPM)

Traction Motor cooling blower.

Transformer Oil cooling blower.

Exhauster.

Shock Grade Motors for Warships

BBL manufactures special Shock Grade motors for the Indian Navy as per the Naval Specification EED-Q-071. These motors are designed to withstand shock levels up to 320G in all three axis.

Multispeed Motors

BBL manufactures multi speed motors for two or three distinct operational speeds by pole changing.

These motors have a single winding for speed ratios of 1:2, eg. 1500 / 3000 rpm.

Two separate windings are used for higher speed ratios.

Pole Amplitude Modulated windings can be given for 4 /6 pole motors. These are in smaller frame sizes as compared to two separate windings.

Sugar Centrifuge Motors

These motors are used for Batch Type sugar centrifuges. These are 3 or 4 speed pole changing motors suitable for speed variation by varying the supply voltage and are used in closed loop control. A special rotor design makes the motor suitable for stable running at even 80% slip.

Motors are available for 750, 1000 and 1250 Kg. Baskets

Cane Un-loader Motors

These TEFC motors are designed with forced cooling and are suitable for starts up to 900 per hour. Built in thermal protection is provided. These are mainly used in cranes used as sugar cane un-loaders. These are available in outputs from 11 kW to 37 kW 6 pole.
