Step Servo Motor 60AHSS280 Incremental ABZ Encoder 1000 Lines 4.2A 2.8N.M Closed-Loop 2 Phase Hybrid Stepper Motors
1. Products Overview
The working principle of the closed-loop step motor is similar to the open loop stepper motor. The key difference is that the closed-loop stepper motor is equipped with the encoder, which is to monitor the actual position of the motor rotor in real time, and feedback this information to the controller. The controller compares the actual and target positions, and then adjust the motor movement to ensure that it works as expected. This closed -loop control method makes the stepper motor more accurately.
The closed -loop stepping motors have the advantages compared with stepping motors and servo motors.
Closed loop stepper motors are relatively quieter and less resonated than stepping motors. At the same time, they can achieve position feedback and control. The correction time is shorter, and no step loss during operation. In terms of energy saving, running stability, and driving higher loads, the closed loop step motor has more advantages.
Compared with the servo motor, the advantages of closed -loop motors are mainly: higher torque at low speed conditions, shorter correction time, accurate positioning, no swing when reach target position, smaller size and lower price etc..
Compared with the traditional open loop stepper motor, the closed -loop step has the following advantages:
1. No step loss problem: Because the closed -loop step motor uses the encoder feedback control, it can correct the position deviation in real time, which will not lead to the phenomenon of throwing.
2. Higher speed and higher accuracy: Because the feedback system is used for control, the closed -loop step into the motor can achieve higher speed and higher accuracy.
3. Simple and easy -to -use: The control system of closed -loop step into the motor is relatively simple. Users only need to write the corresponding program to accurately control the motor
Application:
The closed loop step motor is suitable for automation control systems, which needs higher accuracy and other performance specifications, such as electronics devices manufacturing, CNC machines ( marking, cutting, engraving, milling, etc), robots, medical devices, testing equipment, packaging, microelectronics manufacturing, optical inspection instruments, printing machines, SPMs and other factory automations etc..
