A Squirrel Cage Rotor is a key component of an electric motor, particularly in induction motors. It consists of a cylindrical structure made of conductive bars, usually aluminum or copper, that are short-circuited at both ends by end rings. This design allows the rotor to create a magnetic field when an alternating current flows through it, enabling the motor to convert electrical energy into mechanical energy. The name "squirrel cage" comes from the rotor's resemblance to a small animal cage. This type of rotor is known for its simplicity, durability, and efficiency, making it a popular choice in various applications, including fans, pumps, and industrial machinery.
