Poles of DC Motor. The magnetic poles of DC motor are structures fitted onto the inner wall of the yoke with screws. The construction of magnetic poles basically comprises of two parts. Namely, the pole core and the pole shoe stacked together under hydraulic pressure and then attached to the yoke.

DC Motor - Basics, Construction, Types & Its Application

What is DC Motor? A DC motor is an electric motor that runs on direct current power. In an electric motor, the operation is dependent upon simple electromagnetism. A current-carrying conductor generates a magnetic field, when this is then placed in an external magnetic field, it will encounter a force proportional to the current in the conductor and to the strength of the …
