Question

in an electric motor, which of the following remains fixed and which rotates with the coil? commutator, brush​

Answer 1

Answer:

The commutator rotates with the coil whereas the brush remains fixed.

Explanation:

To answer this question, let us look at the different parts of an electric motor and their functions.

• Commutator - The rotating interface that connects the armature coil with the external stationary circuit.
• Brush - connects the armature and the battery
• Armature core - provides mechanical strength and holds the armature conductors in position.
• Armature coil - It keeps the motor in motion.

From the information above, you realize that the commutator is in motion whereas the brush is stationary.

Answer 2

In an electric motor, the commutator rotates with the coil while the brushes remain fixed.

Explanation:

• In an electric motor, the commutator rotates with the coil while the brushes remain fixed.
• The electric motor consists of various parts such as rotator, stator, and gear along with that bearing and belts are also present to reduce the friction of the electric motor.
• The commutator spins the electric motor and it also reverses the direction of the current.
