Q:

Slip rings are usually made of

A) Aluminium	B) Copper
C) Phosphor Bronze	D) Carbon

Answer & Explanation Answer: C) Phosphor Bronze

Explanation:

A Slip ring is a ring in a dynamo or electric motor which is attached to and rotates with the shaft, passing an electric current to a circuit via a fixed brush pressing against it.

Slip rings are usually made of Phosphor Bronze.

Slip ring motors usually have a 'phase-wound' rotor. This type of rotor has a 3-phase, double-layer, distributed winding consisting of coils used in alternators. The rotor core is made up of steel laminations which have slots to accommodate formed 3-single phase windings.
