Question

To supply the proper current to the armature, a four-pole motor must have four ________ riding on the commutator.

Answer 1

A four-pole motor must have four brushes riding on the commutator to supply the proper current to the armature.

Step-by-step explanation:

In order to supply the proper current to the armature, a four-pole motor must have four brushes riding on the commutator.

The commutator is responsible for reversing the current flow at set points to keep continual motion in the motor. The brushes press against the commutator, creating electrical contact between parts of the commutator during the spinning motion.
