A Slip Ring induction motor can be started with external resistance added in its rotor circuit. But how does external resistance aid in better starting characteristics? Read here to know about the starting arrangement and the role played by the external resistances in obtaining better starting characteristics. Also know about the qualities of slip ring induction motors.

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. Adjusting the resistance allows control of the speed/torque characteristic of the motor. Wound-rotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit; as the motor accelerates ...

27-11-2012· induction motors. This article is devoted to slip ring induction motors. As discussed earlier, a slip ring induction motor is an asynchronous motor, as the rotor never runs in synchronous speed with the stator poles. Learn more about the construction and operation of a slip ring induction motor. Construction Stator:

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.
