Practical Observation of Induction Motor | Parts, Working & Key Parameters
Induction motors are single excited motors with a stator containing winding and a rotor without winding. The stator, made of silicon steel and designed for optimum cooling, produces a rotating magnetic field that induces current in the rotor, enabling it to rotate. Key components include the nameplate, which provides essential specifications, and the rotor, often resembling a squirrel cage due to parallel conductors. The motor operates based on Faraday’s law, where the interaction of magnetic fields generates torque. Important terms include synchronous speed and rotor speed, where the rotor typically runs slower than the synchronous speed, defining it as an asynchronous motor.
