Description
Servo motor refers to the engine that controls the operation of mechanical components in the servo system. Servo motors can be understood as motors that obey control signals and are used to control speed and position accuracy. The speed of the servo motor rotor is controlled by the signal, which is used as an executive component in the automatic control system, and has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc., which can convert the received electrical signal into the angular displacement or angular speed output on the motor shaft.
The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. Servo motor rotor speed is controlled by the input signal, and can react quickly, in the automatic control system, used as an executive component, and has a small electromechanical time constant, high linearity characteristics, the received electrical signal can be converted into the angular displacement or angular speed output on the motor shaft. Divided into DC and AC servomotor two categories, its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases with the increase of torque.

Brushless motor small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, torque stability. The control is complex, easy to achieve intelligence, its electronic commutation mode is flexible, can be square wave commutation or sine wave commutation. The motor is maintenance-free, high efficiency, low operating temperature, small electromagnetic radiation, long life, and can be used in a variety of environments.
2, AC servo motor is also a brushless motor, divided into synchronous and asynchronous motors, motion control is generally used synchronous motor, its power range is large, can achieve a lot of power. Large inertia, low maximum rotational speed, and rapidly reduced with the increase of power. Therefore, it is suitable for low speed and smooth operation applications.
3, the rotor inside the servo motor is a permanent magnet, the driver control of U/V/W three-phase electric electromagnetic field, the rotor rotates under the action of this magnetic field, while the motor comes with the encoder feedback signal to the driver, the driver according to the feedback value and the target value to compare, adjust the rotor rotation Angle. The accuracy of the servo motor is determined by the accuracy of the encoder (number of lines).
The difference between AC servo motor and brushless DC servo motor in function: AC servo is better, because it is sine wave control and torque ripple is small. Dc servo is trapezoidal wave. But DC servo is simpler and cheaper.
