Servo motor is also called the executive motor, or called the control motor. In the automatic control system, the servo motor is an actuator element, its function is to transform the signal (control voltage or phase) into a mechanical displacement, that is, the received electrical signal into a certain speed or angular displacement of the motor. The servo motor has the DC and the AC points.

Spindle servo motor is the drive motor of the spindle in the machine tool processing, which is mainly used to control the speed and position of the spindle, and to improve the movement accuracy and stability in the processing process. The spindle servo motor consists of three parts: servo motor, encoder and driver. The servo motor acts as the drive motor of the spindle load, receives the command signal of the controller, feeds back the spindle speed and position information through the encoder, and then converts the command signal into the actual motor movement through the driver.
There are two kinds of control modes of the spindle servo motor: position control and speed control. The position control is mainly through the encoder to feedback the actual position of the spindle to realize the spindle rotation accuracy and position accuracy control; the speed control is mainly through the controller output control signal to let the servo motor rotate at the specified speed to achieve the purpose of controlling the speed. At the same time, the spindle servo motor also has some special functions, such as acceleration, deceleration control, load control, torque limit and so on.

Spindle servo motor is widely used in all kinds of machine tool processing equipment, such as lathe, milling machine, grinding machine, drilling machine and other machine equipment. Its main function is used to drive the spindle, control the speed and position of the spindle movement, so that the machine tool processing process to achieve the expected precision and efficiency. Among them, the advantage of spindle servo motor is that it can quickly respond to motion control signals, provide high speed and high precision speed and position control, and have certain operation stability and load capacity.
The application of spindle servo motor can improve the precision of machine tool processing and increase the production efficiency. In the automatic machine tools, CNC machine tools and other high-precision machine tools is an essential part, to support its high-speed, high-precision processing requirements. At the same time, the spindle servo motor can also be applied in industrial automation, aerospace, medical equipment and other fields, to provide automation drive support for various industries.
1. physical construction
Servo-spindle motor is a servo-motor with built-in spindle, which integrates spindle, servo motor and synchronizer. While the ordinary servo motor is only an independent servo motor, which needs to be coordinated with other mechanical equipment to achieve relevant functions.
2. control method
The servo spindle motor uses the spindle controller to control the speed of the spindle, and the servo controller to realize the control of torque and speed. The control of ordinary servo motor is mainly based on three aspects of position, speed and torque, and its control mode is more complex.
3. performance requirement
Servo spindle motor is mainly suitable for high-speed rotation and high-precision processing requirements, requiring high control accuracy, fast response speed, and for the spindle and servo motor control at the same time. The control demand of ordinary servo motor is mainly in the position, speed, torque of these three aspects have a very high requirements, need to ensure the control accuracy and performance.
4. Main schematic diagram of the servo motor
Forward and back rotation: speed error + / -1rpm, 3000 RPM acceleration and deceleration for 1 second.
Independent quasi-stop: high precision (0.03) positioning, convenient to up and down the workpiece robot.
Rigid tapping: up to 3000 RPM rigid tapping, minimum power tooth M3.
C-axis function: the separation accuracy can reach + / -1pulse, and the vehicle and milling accuracy can be as low as 0.01rpm.
Low speed heavy cutting: instant 3 times overload, ensure the stable cutting speed, suitable for casting processing.
High-speed precision machining: constant power output above 1500 RPM, stable speed, guaranteed finish.
Strong applicability: it can be used with many domestic and foreign upper machines (CNC system, PLC, etc.).
Powerful secondary development: you can customize special features according to customer requirements.
