Inductive kick causes

Inductive kick is

The brushes in dc machine are normally placed electrically in interpolar region, to

Commutator is a

Commutator action is analogous to _________ in analog electronics.

For a four pole, 16 slot armature with two coil-side/slot having wave connected progressive winding has single turn coils. The commutator pitch for the machine should be

While the operation of dc motor, there are sparkings at the commutation observed. These can be happening due to

The armature rotation in the dc machine and the magnetic field are independent of each other and obey laws of conservation of energy.

A 200 V dc machine working at rated speed. Voltage across the commutating terminals should ideally be
