Performance comparison of servo motor and stepping motor.
Stepper motor as an open-loop control system, and modern digital control technology has the essential link.
In the current domestic digital control system, stepping motor is widely used.
With the emergence of digital AC servo system, AC servo motor is more and more used in digital control system.
In order to adapt to the development trend of digital control, most of the motion control system adopts stepping motor or full digital AC servo motor as executive motor.
Although they are similar in control mode (pulse train and directional signal), there are great differences in performance and application.
The use performance of the two are compared.

It is very helpful to improve the stability of the low speed control of the servo motor.
But there is no direct effect to improve the accuracy of position control.
There are, of course, software compensation that is similar to pitch compensation,
Can improve the physical resolution of the single lap, so as to improve the accuracy of positioning control MITSUBISHI HC-RF503.
This can be effectively used in the use of the robot control of the indexing table.
It is also because of the application of splicing technology,
The rotary encoder will be more widely used in the high precision servo control in the harsh environment.
The use of rotary encoder with 224/ in the servo motor has been used in the servo motor MITSUBISHI HC-RF503.
Encoder serial communication system, the communication frequency can only be limited to 10M. Motor: HA-LH type.
According to the types of power supply: can be divided into DC motor and AC motor.
The structure and working principle of DC motor can be divided into four parts: brushless DC motor and brushless DC motor.
Brushless DC motor can be divided into: permanent magnet DC motor and DC motor.
DC Motor Division: Series DC motor, DC motor, DC motor and DC motor.
Permanent magnet DC Motor Division: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and aluminum nickel Gu Yongci DC motor. Type: HF-KE servo motor, low inertia, low power.
Rated output power: 0.75kw.
Rated speed: 3000r/min.
Electromagnetic brake: No.
Oil seal: No.
Servo motor can make control speed, position accuracy is very accurate,
The voltage signal can be converted to torque and speed to drive the control object.
Servo motor rotor speed is controlled by the input signal, and can quickly response,
In an automatic control system, used as an actuator,
With electromechanical time constant, high linearity, initiating voltage characteristics,
The signal can be converted into a motor shaft on the angular displacement or angular velocity output.
Divided into DC and AC servo motor two major categories, the main features are,
When the signal voltage is zero, the rotation speed increases with the increase of torque.
Servo amplifier terminals are used to reduce the required wiring time.
The connector is located in front of the servo amplifier, which is convenient for cable connection.
The gain adjustment can be easily carried out by the real-time automatic tuning function.
