Chapter 6: Induction Motors Engineering360
In induction machines, the rotor voltage (which produces the rotor current and the rotor magnetic field) is not physically connected by wires to the rotor windings it is induced in the rotor. The main advantage of induction motors is that there is no need for dc field current to run the machine. An induction machine can be used as a motor or a generator.

Induction motor Wikipedia
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor''s rotor can be either wound type or squirrelcage type.
