Slip Ring Rotor

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.

Slip ring rotor.

In slip ring motors the rotor resistance is increased by adding external resistance so the slip is increased. As the motor reaches its base speed full rated speed after the removal of external resistance and under. Instead of bars in this motor three windings are used. Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit.

It is a type of motor where its external circuit is connected using some rings. It can improve mechanical performance simplify system operation and eliminate damage prone wires dangling from movable joints. Moflon has been manufacturing and supplying slip rings and rotary unions to companies contractors and other end users for more than 30 years now. Adjusting the resistance allows control of the speed torque characteristic of the motor.

To overcome this problem the slip ring induction motor comes into the picture. Since the rotor resistance is high the slip is more thus it s possible to achieve pull out torque even at low speeds. The working principles and stator construction of the slip ring induction motor are exactly the same as that of the squirrel cage motor. The motor which employing the wound rotor is known as a slip ring induction motor or phase wound motor.

As a leading designer and manufacturer of slip rings our solutions are applicable even in demanding applications. As the motor accelerates. Definition of slip ring motor. Because of various advantages like low initial current high starting torque and improved power factor it is used in applications that require high torque cranes and elevators.

Slip ring induction motor is one of the types of 3 phase induction motor and is a wound rotor motor type. However the rotor construction of the slip ring motor is quite interesting. What is slip ring induction motor. A wound rotor motor uses three slip rings typically made of copper or a copper alloy mounted to but insulated from the motor shaft.

A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. This rings attached with high resistance acts as an external circuit for the rotor. A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. The slip ring brushes made of graphite are connected to a resistive device such as a rheostat.
