Synchronous Motors are a type of AC motor in which the rotor rotates at a speed that is synchronised with the frequency of the supply current. This means the rotor and the rotating magnetic field generated by the stator operate at the same speed, making synchronous motors ideal for applications requiring precise, constant speed under varying loads. These motors are available in various configurations, including permanent magnet, reluctance, and traditional AC-excited types.
Features
- Constant Speed: Operates at a fixed speed regardless of load, ideal for processes requiring precise control.
- High Efficiency: Particularly in permanent magnet and reluctance motor designs, offering energy savings and reduced operational costs.
- Power Factor Correction: Capable of operating with a leading power factor, reducing reactive power in electrical systems.
- High Torque Capability: Especially in applications like generators or where precise torque control is needed.
- Minimal Slip: Unlike induction motors, synchronous motors have minimal to no slip, maintaining synchronised speed.
