Dc Motor By Nbe Motors Pvt. Ltd.

New Bharat
Electricals DC Motors are applicable most wherever variable speed control
drives are used. The speed control of DC Motors by armature control or field
control at constants torque & for constant continuous operation.
Due to incorporation with latest technology which ensures safe & trouble-free
operations under critical conditions.

Range : SCR-Rated DC Motors with 1 through 30 Horsepower with base speed
300 to 3000 Rpm, Arm. Voltage 12, 24,36 110v, 220v, 440v avail on request. DC
Motors with various types of constructions are available from 80 to 225mm frame
size.

Standards : Performance of our motors confirms always as per IS-4722.
Temp-rise are well within 45c (ambient temp.)

Construction Features :




High Quality steel
frame stator body are made from fabricated. The V-weld at meeting corner of
the ends of plate impart heavy strength to the yoke.


Armature
laminations are of high quality electrical grade steel for low iron losses &
high efficiencies i.e. (CRNGO.)


Commutator: (The
Heart of DC machine) Made from silver-copper-alloy. Electrolytic copper
segments insulated from one another with mica. Riser connections are the TIG
welded for minimum resistance and maximum strength.


Armature windings
are impregnated with synthetic resin, a high dielectric strength varnish and
properly baked at designed temp. to give complete protection against damage
from moisture, acids and alklies.


End-shields covers
are from cast iron with proper machining.


Main poles are
made from thick laminations (G.I.Sheet) to reduce eddy-current losses.



Interpoles are
fitted in motors in order to achieve better communication.


High - Electro -
graphite carbon brushes used which display best running properties under
varying loads.


Ventilation: Our
motor equipped with SCREEN PROTECTED DRIP PROOF (SPDP) & TOTALLY ENCLOSED
(TE). External force cooling is provided with blower mounted motor.



LARGE CONDUIT BOX
that meets all electrical codes for volume and conduit entrances and may be
rotated in 90 degree increment.
