Permanent magnet Synchronous Motor


Definition of Synchronous Motors:

Permanent magnet Synchronous Motor, Electric motors that operate in synchrony with the frequency of an alternating current (AC) power supply are known as synchronous motors. They are frequently utilized in industrial settings where exact speed control and excellent operational efficiency are necessary.

The main feature of synchronous motors is that the rotor rotates at the same rate as the stator’s revolving magnetic field. Permanent magnets or an electromagnet on the rotor, which produces a magnetic field that locks in step with the revolving magnetic field of the stator, are used to achieve this synchronous rotation.

Synchronous motors have no slip, in contrast to asynchronous motors (sometimes referred to as induction motors), which rely on slip to produce torque. This indicates that regardless of the load, the rotor speed of a synchronous motor is constant. An AC power supply’s frequency and voltage can be changed to accurately control the synchronous motor’s speed.

Synchronous motors have a number of benefits. With a power factor close to unity and good efficiency across a variety of loads, they require less reactive power from the power grid. These motors are suited for applications needing continuous speed, such as generators, compressors, and precision machinery, and they also have great speed stability.

However, synchronous motors need a separate power source to power the magnetic field of the rotor. This power source might be a DC power source or an excitation system connected to an AC power source. They are also more expensive and sophisticated than asynchronous motors.

The frequency of the AC power supply determines the rotational speed of synchronous motors, which are electric motors that rotate at a fixed pace. They are ideal for a variety of industrial applications because of their great efficiency, superb speed stability, and accurate control.
