Question

Explain the function of brushes in an electric motor

Answer 1

The functions of brushes in an electric motor are:-

• Brushes are employed in electric motors to transfer energy from the rotating armature coils to the rotor's fixed wires. Split rings are used to give unidirectional current to the rotor coils, causing them to rotate in the same direction and generate torque.
• Brushes have the function of making contact with a revolving conductor (the commutator). These were originally wire bundles that were stretched beyond the commutator. One time, a few wire strands would be in contact. Of course, these bundles resemble "brushes."
• However, things have improved, and the brushes are now made of conductive materials, low-friction, solid. Graphite of many sorts is commonly used. These brushes need to be held against something.

Answer 2

1. Brushes are used in electric motors to transfer energy from the rotating armature coils to the fixed wires of the rotor.
2. Split rings are used to supply unidirectional current to the rotor coils, which causes them to rotate in the same direction and generate torque.
3. Brushes are used to make contact with a revolving conductor (the commutator).
4. Originally, these were wire bundles that had been stretched beyond the commutator.
5. A few wire strands would come into contact at one point.
6. These bundles resemble "brushes."
