Product Q&A
Q:Will this closed-loop stepper motor lose steps?
A:
No. The built-in encoder realizes real-time position feedback and automatic compensation, which thoroughly avoids step loss under heavy load or high speed.
Q:What is the maximum working speed?
A:
The recommended rated speed is 0~800 RPM, and the maximum no-load speed can reach 3000 RPM with stable torque.
Q:Can I use it to replace the original open-loop motor directly?
A:
Yes. The flange size and installation dimensions are fully consistent with open-loop motors, no need to modify mechanical structures.
Q:What are the differences between standard type and brake type?
A:
The brake model adds a brake structure to prevent loads from falling, and its body length is 40mm longer than the standard one.
Q:What drivers are compatible with these motors?
A:
42mm matches BH42; 57mm matches BH57/BH57-H/BH57-BK; 86mm matches BH86 drivers.
