3. Introduction: The type of synchronous motor whose r otor is made of permanent magnet and its stator is identical to that of an induction motor. The presence of magnetic field on the rotor allows rotor to move at synchronous speed with stator field. Widely used in industry due to its high performance characteristics: Compact High efficiency (no excitation current) Smooth torque Low acoustic noise Fast dynamic response (both torque and speed) A s ynchronous motor differs from an asynchronous motor in the relationship between the mechanical speed and the electrical speed.

4. Advantages & Disadvantages Elimination of field copper loss. High power density. Lower rotor inertia. More robust construction of motor. Higher efficiency. Loss flexibility of field flux control Re-magnetization effect Higher cost
