Motor Division - Special Products
Torque Motors:
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 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.
These motors can be offered in various types of
mounting.
Low Vibration Motors:
BBL manufactures Low vibration motors for the machine
tool industry. These motors are offered with vibration level upto
Precision class C ( 0.28 mm/sec) or ( 5 microns peak to peak).
 Loco
Auxiliary Motors and 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.
 BBL
also supplies the complete blower for the Traction motor cooling
as well as the Transformer Oil cooling applications for both the
conventional as well as the latest Three Phase locos.
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 upto 320G in all the 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 Unloader
Motors:
These TEFC motors are designed with forced cooling
and are suitable for starts upto 900 per hour. Built in thermal
protection is provided. These are mainly used in cranes used as
sugar cane unloaders. These are available in outputs from 11 kW
to 30 kW 6 pole.
