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 squirrel-cage type.

Now, induced current in rotor will also produce alternating flux around it. This rotor flux lags behind the stator flux. The direction of induced rotor current, according to Lenz's law, is such that it will tend to oppose the cause of its production.; As the cause of production of rotor current is the relative velocity between rotating stator flux and the rotor, the rotor will try to catch up ...

More than 85% of motors used in industries are induction motors. It has a constant speed operation. It is a singly fed machine i.e. the rotor does not need to be excited as in the case of synchronous motor. It runs at the speed little less than the synchronous speed. Hence it is called as asynchronous machine.

Induction Motor: Working Principle, Types, & Definition ...

Synchronous speed is the speed of rotation of the magnetic field in a rotary machine, and it depends upon the frequency and number poles of the machine. The induction motor always runs at speed less than its synchronous speed. The rotating magnetic field produced in the stator will create flux in the rotor, hence causing the rotor to rotate. Due to the lag between the flux current in the rotor ...

Synchronous Generator Construction and Working Principle

The principle of operation of synchronous generator is electromagnetic induction. If there exits a relative motion between the flux and conductors, then an emf is induced in the conductors. To understand the synchronous generator working principle, let us consider two opposite magnetic poles in between them a rectangular coil or turn is placed as shown in the below figure.
