In the Commutation Process?

The commutation in DC machine

or more specifically commutation in DC generator is the process in which generated alternating current in the armature winding of a dc machine is converted into direct current after going through the commutator and the stationary brushes. ... It is called commutation period.

What is commutation in a motor?

Put simply, commutation is the process of switching the current in the motor phases to generate motion. Brushed motors have physical brushes to achieve this process twice per rotation, while BLDC motors do not, hence the name. Due to the nature of their design, they can have any number of pole pairs for commutation.

What is meant by commutator in DC generator?

A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. ... By reversing the current direction in the rotating windings each half turn, a steady rotating force (torque) is produced.
