A synchronous motor and an induction motor are two widely used types of AC motors in electrical and electronic engineering, and they differ significantly in their operating principles, construction, speed characteristics, starting methods, and applications. The fundamental difference lies in the principle of operation. A synchronous motor operates on the principle of magnetic locking between the rotating magnetic field produced by the stator and the magnetic field of the rotor. The rotor is excited by direct current, creating a constant magnetic field that locks in step with the stator’s rotating magnetic field. As a result, the rotor rotates at exactly the same speed as the rotating magnetic field, which is called synchronous speed. In contrast, an induction motor operates on the principle of electromagnetic induction. In this motor, the stator produces a rotating magnetic field that induces current in the rotor conductors. The interaction between the induced rotor current and the stator magnetic field produces torque, causing the rotor to rotate. However, the rotor never reaches synchronous speed because relative motion between the stator field and rotor is required to induce current. Another
