1. Products Overview
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..
The characteristics of closed-loop stepping motor
1. Compared with the open-loop step motor, the closed-loop step motor does not lose steps or can be easily corrected. It can ensure the accurate positioning of the motor, reduce the motor vibration, and run more stable.
2. Compared with the servo motor, the closed-loop step motor does not require complex parameter adjustment, such as gain adjustment etc., which is more convenient to use. It does not vibrate at high speed, and is stable at zero speed, and the position response is fast. It is suitable for short distance fast start and stop occasions. It provides higher torque with smaller installation size.
3. The closed-loop step into the motor improves the high speed performance of the moto with higher torque.
4. The closed-loop motor effectively reduces the heat generated by the motor, as the drive output current changes as the load and speed change.
5. The closed-loop motor has fasten response time. The output of the position response and the input control signal are almost synchronized in real time, so it is especially suitable for the applications which needs zero speed stop, fast start and stop within short distance.
6. Closed-loop step motor runs more smoothly and has higher accuracy. It uses vector control and advanced filtering technology to achieve better performance.
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..
