• Stator: This is the stationary element of the induction motor. The stator is a small
cylindrical frame which carries the cylindrical core of the rotor. It features
different slotted stampings to carry three-phase windings. The windings of the
stator have 120 degrees separation.
• Rotor: This is the rotating part of the motor. The rotor features laminated
cylindrical slots with copper or aluminum conductors that have joined ends. It is
the shaft of the motor.

The rotor of the three-phase induction motor is classified as phase wound rotor or slip
ring rotor and squirrel cage rotor. Among the two, the squirrel cage rotor is one of the
most common ones.
