Question

how is the interpols polarity decided in a d.c motors??​

Answer 1

Answer:

Interpoles. Interpoles are designed in DC motors to overcome the effects of the armature reactance and the self-induction of the machine. ... This creates a changing magnetic field equal to and opposite that of the armature, thereby cancelling the effect. Polarity of an interpole depends on the direction of rotation.
