Question

Why do we use slip rings in motors?

Answer 1

The use of slip rings

The slip rings have the following importance

1. It uses a low current to start.
2. The starting power is increased.
3. The total impedance is stabilized by the use of external resistance through the element that limits current.
4. The starting torque is much higher compared to other motors.
5. The speed of the induction motor can be controlled.

Hence, the slip rings have a lot of advantages.
