Estun servo motor - the structure and working principle of AC servo motor
structure
AC servo motors are usually single-phase asynchronous motors, with two structural forms: squirrel cage rotor and cup rotor. Like ordinary motors, AC servo motors are constructed of a stator and a rotor. There are two windings on the stator, namely the excitation winding and the control winding, and the two windings are ...

Estun servo motor - the basic application of AC servo motor
Material metering
The measurement of powdery materials is commonly used in the way of screw measurement. The purpose of measurement is achieved by the number of turns of the screw rotation. In order to improve the accuracy of measurement, the speed of the screw is required to be adjustable, and the position positioning is accurate.

Estun servo motor - the setting method of important parameters of servo drive
1. Positional proportional gain
Sets the proportional gain of the position ring adjuster. The higher the set value, the higher the gain, the greater the stiffness, and the smaller the position lag under the same frequency command pulse. However, too large a value may cause oscillations or overshoots. The parameter values are determined by the specific servo model ...

Estun servo motor - the difference between servo motor and control motor and how to choose a motor
What are the main differences between the two?
1. The way of control is different
Stepper motor: The rotation angle is controlled by controlling the number of pulses, and one pulse corresponds to a step angle.
Servo motor: The angle of rotation is controlled by controlling the length of the pulse time.
2. Work ...

Estun servo – the difference between servo motor and ordinary motor
There are many types of motors, and the ordinary motor we commonly use is the induction motor, although it and the servo motor are both motors, there are certain differences:
1. The speed of ordinary motors is too fast, the torque is too small, and because there is no feedback from itself, it is usually impossible to achieve accurate control.

Estun servo motor - introduction to the control mode of AC servo motor
1. Amplitude and phase control mode
The amplitude and phase are controlled, and the speed of the servo motor is controlled by changing the amplitude of the control voltage and the phase difference between the control voltage and the excitation voltage. That is, the amplitude and phase of the control voltage UC are changed at the same time.
2. Phase control mode
