A synchronous motor is an AC motor whose rotation speed is synchronized with the AC frequency of the power supply. This type of motor is usually used in situations where precise control of speed and position is required, such as large industrial equipment, power plants, wind power systems, etc.

Working principle
The working principle of synchronous motors is based on the concepts of electromagnetic induction and synchronous rotation. When the three-phase winding of the motor is connected to three-phase AC, a rotating magnetic field will be generated. Since the rotor of the motor (usually a permanent magnet or a rotor with an exciting winding) is designed to interact with this rotating magnetic field, the rotor will rotate following the rotation of the rotating magnetic field. Since the rotation speed of the rotating magnetic field is directly related to the frequency of the power supply, the rotation speed of the rotor is also synchronized with the frequency of the power supply.

peculiarity
Precise speed control: Synchronous motors are able to precisely control the rotation speed because they are directly dependent on the frequency of the power supply. By changing the frequency of the power supply, the speed of the motor can be precisely adjusted.

High efficiency: Synchronous motors have high efficiency in operation because their rotation speed is synchronized with the power supply frequency, reducing energy loss.

Good speed control performance: Compared with asynchronous motors, synchronous motors have better speed control performance. They enable smooth, precise speed regulation over a wider speed range.

Suitable for large equipment: Synchronous motors are usually used to drive large industrial equipment, such as compressors, pumps, fans, etc. They can withstand high loads and operate at high speeds.

Excitation system required: Unlike asynchronous motors, synchronous motors usually require an external excitation system to generate the required magnetic field. The excitation system can be a DC power supply or a separate excitation winding.

Application field
Synchronous motors are widely used in the following fields:

Power plant: Used to drive a generator that converts mechanical energy into electrical energy.
Wind power generation: In wind power generation systems, synchronous motors are used as generators to convert the rotational energy of wind turbines into electrical energy.
Pumps and compressors: Used to drive large pumps and compressors to provide fluid transfer and pressure increase.
Industrial equipment: Used to drive various industrial equipment, such as machine tools, rolling mills, paper machines, etc.
Transportation: In some high-speed trains and electric vehicles, synchronous electric motors are used to provide power.
In short, synchronous motor has been widely used in various fields for its precise speed control, high efficiency and good speed regulation performance.
