Estun servo motor - the structural composition of the servo control system
A servo control system is a feedback control system that is used to accurately follow or reproduce a process. In many cases, the servo system refers specifically to the feedback control system in which the controlled quantity (the output of the system) is the mechanical displacement or displacement velocity and acceleration, and its function is to make the mechanical displacement of the output (or ...

Estun Servo Motor – The difference between a servo motor and a stepper motor
1. Different ways of control
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. The workflow is different
Stepper motor ...

Estun Servo Motor - AC Servo Motor Vibration Fault Analysis
Mechanical
1. Bearing
The bearing clearance on the lead screw housing is too large after wear, or the bearing roller elements and cages are severely worn due to the lack of grease in the bearing, resulting in excessive loads. After bearing wear, the clearance is too large, which will cause the coaxiality error between the center of the motor rotor and the center of the lead screw.

Estun Servo Motor – The stepper motor controller is different from the servo motor controller
First, the working principle is different
Stepper motor controller: It is an electronic product that can send out a uniform pulse signal, and the signal it sends out enters the stepper motor driver, which will be converted by the driver into a strong current signal required by the stepper motor to drive the stepper motor to run. Stepping ...
