0.45N.m Closed-loop 2 Phase Hybrid Stepper Motors
1. Products Overview
The closed loop stepping motor is a high-precision motion control
motor. By adding the position sensor such as the encoder, the
actual position of the motor is fed back to the driver or
controller. The closed loop step motor has the advantages of high
precision, high stability, and low vibration, and it is suitable
for applications with higher accuracy requirements.
Working principle:
The working principle of the closed loop step into the motor is
similar to the regular stepper motor, and the difference is that
there is a position feedback by encoder, which enables higher
accuracy and higher torque, lower vibration etc.
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..
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..
