Wound-rotor induction motors. Some special induction motors are constructed with insulated coils in the rotor similar to those in the stator winding. The rotor windings are usually of a three-phase type with three connections made to insulated conducting rings (known as slip rings) mounted on an internal part of the rotor shaft. Carbon brushes provide for external electric connections.

Working Principle of an Induction Motor

According to Faraday's Law of electromagnetic induction, the EMF induces in the conductor. As the rotor circuit is completed by the external resistance or by the end ring, the rotor induces an EMF which causes the current in the circuit. The direction of the rotor induces current is opposite to that of the rotating magnetic field.
