The pole core and Pole shoes of Universal Motor is made up of
Right Answer is:
Silicon Steel
SOLUTION
The magnetic frame, pole core, and pole shoe of the universal motor are made of silicon steel stampings. These stampings are insulated from each other by a varnish layer. The hysteresis losses are very small in silicon steel, and eddy current losses are reduced due to stampings. The field winding made of enameled copper is wound around the poles to produce the required flux.
