Bharat Bijlee Special 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).

BBL manufactures TEFC three phase Torque motors with Type 'MT'. These motors are similar to standard induction motors but with a modified high resistance rotor design.

 

The starting torque of these motors is maximum and it has almost linear torque speed characteristics with zero torque at synchronous speed.

 

These motors are used in special applications like Roller Table motors, High speed tapping machines, clamping devices etc. These motors can be offered in various types of mounting.

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.

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, for example: 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.
