When the rotor is installed in a motor, three leads are brought out from the rotor winding to solid conducting____________ .
A)collector rings
B)end rings
C)slip rings
D)bearings

Question

Quizplus · Accepted Answer

The three leads from the rotor winding are connected to slip rings which are solid conducting rings that are mounted on the rotor shaft. The slip rings make contact with brushes that are stationary and connected to external circuitry. As the rotor turns, the brushes maintain contact with the slip rings, transferring power to and from the rotor winding. Slip rings are used to provide the electrical connection to the rotor winding while allowing the rotor to rotate without tangling the wires. Collector rings and end rings are typically used in DC motors, while bearings are used to support the rotor shaft and allow it to rotate smoothly. Therefore, the best choice is C) slip rings.
