Product Q&A
Q:What is the maximum speed of your closed-loop stepper motor?
A:
The recommended rated working speed is 0~800 RPM, and the maximum no-load speed can reach up to 3000 RPM.
Q:What is the difference between single shaft and dual shaft motors?
A:
They have the same electrical performance. Single shaft is for single-side transmission, while dual shaft supports double-end power output and manual adjustment.
Q:Are NEMA17 motors equal to 42mm stepper motors?
A:
Yes. NEMA17 is the North American standard, which corresponds to our 42mm flange mounting size.
Q:Does closed-loop stepper motor have step loss problem?
A:
No. Built-in encoder realizes position feedback, which completely eliminates step loss and improves positioning accuracy.
Q:Can open-loop and closed-loop motors share the same mounting structure?
A:
Yes. Motors with the same flange size have identical installation dimensions and are fully interchangeable.
