What is the difference between closed-loop stepping motor and traditional stepping motor
Release Time:2019-11-08 11:08:36    Page views:2105
The traditional stepper motor is open-loop control, which may be lost in actual use. The closed-loop stepper motor is equipped with a high-precision encoder on the stepper motor. The servo control algorithm is used to realize the control of torque exchange, speed loop and position loop
What is the difference between closed-loop stepping motor and traditional stepping motor
The closed-loop stepper motor not only retains the characteristics of the traditional stepper motor with large low-speed torque, but also has the ability of 1.5 times of short-time overload output, which improves the dynamic response ability of the stepper motor.
The current control of traditional stepping motor is open-loop control, and the output current is not subject to load selection. The remaining part of electric energy will be consumed in the form of heat energy, which will be converted into motor heating.
The closed-loop stepping motor adopts the pure servo closed-loop control algorithm, the size of the output current is determined by the load, most of the electrical energy will be converted into mechanical energy, which improves the power and reduces the temperature rise of the motor.
Characteristics of servo products

The closed-loop stepping motor control system is a type of control system. The specific content refers to: a part or all of the output of the control system is sent back to the input end of the system through certain methods and equipment, then the response information is compared with the original input information, and then the results of the comparison are applied to the system for control to avoid the system deviating from the predetermined policy. The closed-loop stepping motor control system uses negative response It is an active control system which is composed of positive signal path and response path, also known as response control system.
