Slip Ring Rotor Of Induction Motor

The motor which employing the wound rotor is known as a slip ring induction motor or phase wound motor.

Slip ring rotor of induction motor.

The working principles and stator construction of the slip ring induction motor are exactly the same as that of the squirrel cage motor. Production of high starting torque with slip ring induction motor. It can improve mechanical performance simplify system operation and eliminate damage prone wires dangling from movable joints. It is not advised to start a slip ring induction motor with its rotor terminals shorted.

It is most widely used for industrial applications due to its self starting attribute. The slip ring induction motor has two distinctly separate parts one is the stator and other is the rotor. Slip ring induction motor is one of the types of 3 phase induction motor and is a wound rotor motor type. A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure.

It is a type of motor where its external circuit is connected using some rings. An induction motor is an electrical device that converts electrical energy into mechanical energy. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. Adjusting the resistance allows control of the speed torque characteristic of the motor.

As the motor accelerates. The rotor is wound for the same number of poles as that of the stator. However the rotor construction of the slip ring motor is. This rings attached with high resistance acts as an external circuit for the rotor.

This external circuit helps in developing a high starting torque compared to a squirrel cage type. 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. In a version of the ac induction motor referred to as a wound rotor motor slip rings are used not for transferring power but for inserting resistance into the rotor windings a wound rotor motor uses three slip rings typically made of copper or a copper alloy mounted to but insulated from the motor shaft. Characteristics of slip ring induction motor.

Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit. It consists laminated cylindrical core which has a semi closed slot at the outer periphery and carries three phase insulated winding. What is slip ring induction motor.
