Slip Ring Rotor Winding

However the rotor construction of the slip ring motor is quite interesting.

Slip ring rotor winding.

Rotor the rotor of a squirrel cage motor is a set of bars which are short circuited by end rings. Each phase of winding is connected with the slip ring. What is a slip ring induction motor. This has to do with the windings on the rotor and the use of slip rings.

Bar straps or wires are used for winding. For ease of understanding instead of the current 24 slots winding let s use a 12 slot winding. Also rotor windings are connected through slip rings to external resistance. Let s see how the slip ring rotor does it.

Name one disadvantage of slip ring induction motor and squirrel cage induction motor. This construction of the rotor is aimed at reducing the phase difference. These slip rings are insulated from the rotor shaft. As for the slip ring motor the rotor has the same winding as the stator.

Instead of bars in this motor three windings are used. Adjusting the resistance allows control of the speed torque characteristic of the motor. Construction the construction of the slip ring motor is more complicated than the squirrel cage. As it names wound rotor the rotor is wound with a 3 phase windings.

A wound rotor motor also known as slip ring rotor motor is a type of induction motor where the rotor windings are connected through slip rings to external resistance. A motor with a wound type rotor is known as a slip ring induction motor. As the motor accelerates. A large number of rotor turns will increase the secondary voltages and reduce the current that flows through slip rings.

A wound rotor motor uses three slip rings typically made of copper or a copper alloy mounted to but insulated from the motor shaft. The slip ring brushes made of graphite are connected to a resistive device such as a rheostat.
