How Slip Ring Induction Motor Works Infoupdate Org Slip ring induction motors are a type of ac motor where external resistor connected to the rotor by means of slip rings. the key components of this type of motor include a stator, a rotor, and slip rings connected to the rotor. This article encompasses the working principle of slip ring induction motor, construction, speed control, resistance calculation and its applications.
How Slip Ring Induction Motor Works Infoupdate Org First, according to faraday's law of electromagnetic induction, an electromotive force is induced in the bars. because the rotor bars are short circuited by the end rings, this induced emf generates a current to flow through the rotor bars. These slip rings are mounted on the motor shaft and bear the brushes. this arrangement allows the insertion of external resistance in series with each phase of the rotor for starting or speed control purposes. when running normally, the slip rings are short circuited. Slips rings are connected to the external high resistance circuit. the addition of these rings along with the external high resistance increases the resistance and decreases the inductive reactance. the function of a three phase slip ring induction motor is shown in the figure below. The fundamental operating principle of a slip ring motor is based on the theory of electromagnetic induction, similar to other induction motors. when a three phase ac supply is given to the stator windings, it produces a rotating magnetic field.

The slip ring induction motor has high starting torque and low starting current because of the external resistance. the speed is maximum at no load and reduces according to the increases in the load. Slip ring induction motor is also known as wound rotor induction motor . slip ring induction motor is used to convert electrical energy into mechanical energy. In slip ring motors, the rotor winding is connected to slip rings, allowing for the addition of external resistances. these external resistors influence the current flowing through the rotor and consequently affect the speed torque characteristic of the motor. Slip ring motors, by connecting a suitable starting resistor in the rotor circuit, effectively limit the starting current while increasing starting torque, ensuring a smooth start. after startup, the external resistor can be removed, allowing the motor to enter normal operation.
