The traditional three-phase induction motor equipped with a typical squirrel-cage rotor is one of the most popular types of electrical machines for its excellent features [].For further improvement of electromagnetic performances, some researchers focus on the innovation of motor topologies.
A squirrel cage motor is an induction motor that gets its name from its unique rotor design, which resembles a spinning squirrel wheel. In this motor, the rotor consists of laminated iron cores arranged in a cylindrical shape, with conducting bars placed parallel to the cores. These bars are short-circuited at the ends by conducting rings ...
At its simplest, a squirrel cage motor, or squirrel cage induction motor, is an electric motor that harnesses the principle of electromagnetic induction to generate motion. It's a type of asynchronous motor, which means that the electric current in the rotor (the rotating part of the motor) needed to produce torque – or rotating force ...

Squirrel cage motors maximize electromagnetic induction by utilizing rotor bars to interact with the stator's EMF. The stator usually contains windings of wire which carry an AC current; this current changes in sync with a sinusoidal curve (or "alternates"), which changes the current direction in the wire windings.
The squirrel cage rotor is a crucial component of a squirrel cage induction motor. It is designed to provide the necessary torque and efficiency for the motor's operation. The design of the squirrel cage rotor involves determining the number of rotor bars, the shape of the bars, and the end rings.
Squirrel cage motors are one of the most widely used types of electric motors in various industrial and residential applications. They are known for their simplicity, robustness, and efficiency.
