AC servo motor is a machine that converts electrical energy into mechanical energy, and it has a wide range of applications in industrial automation, aerospace, transportation, electronic equipment, and military equipment. The following is a detailed introduction to AC servo motors:


1、 Definition and Classification

The AC servo motor is mainly composed of an electromagnet winding or distributed stator winding used to generate a magnetic field, and a rotating armature or rotor. According to the type, it can be divided into AC asynchronous servo motors and AC synchronous servo motors. With the development of technology, new permanent magnet AC servo motors have been rapidly developed due to their superior performance.


2、 Working principle

The working principle of communication servo motors is mainly based on phase shift and frequency change to control the steering and speed of the transmission shaft. It cannot directly control the magnitude of the current, but can achieve changes in motor speed by adjusting the power supply frequency, and achieve motor reversal by changing the phase of the motor's electrification. In addition, AC servo motors are equipped with specialized drivers that determine the current position of the rotor based on the photoelectric encoder or Hall device inside the servo motor, and determine the three-phase output state of the driving motor, thereby achieving efficient and smooth operation.


3、 Characteristics and advantages

High precision: AC servo motors have high control accuracy and can achieve precise control of position and speed.

High stability: The closed-loop control mechanism enables it to suppress external disturbances and internal fluctuations, improving the stability of the system.

Wide speed range: Especially for permanent magnet AC servo motors, their speed range is wide and their low-speed performance is superior.

High efficiency: The driver of the AC servo motor adopts advanced control algorithms and efficient power conversion technology, which improves the overall efficiency of the system.

Easy maintenance: Although the cost of AC servo motors is relatively high, their maintenance is relatively simple and their service life is long.


4、 Application Fields

AC servo motors are widely used in the following fields:

Industrial automation: In equipment such as CNC machine tools, printing machines, packaging machines, etc., precise control of motor speed and position is used to improve production efficiency and product quality.

Transportation: Used as a drive system for electric vehicles, elevators, and other equipment to improve the vehicle's power performance and ride comfort.

In electronic devices such as printers and scanners, stable control of the equipment is achieved by precisely controlling the speed and position of the motor.

Military equipment: such as missile guidance systems, radar antenna drives, etc., to improve the accuracy and reliability of equipment.
