CH28-400-30-S Gear Motor FAQ
Q: What is the output RPM of CH28-400-30-S?
A: With a 4-pole 400W motor running at 1380RPM, the 30:1 reduction ratio delivers a rated output speed of ~46RPM, ideal for slow, steady conveyor movement.Q: Can this gear motor be mounted vertically?
A: No, the CH prefix stands for horizontal foot-mounted design. For vertical installation, you can choose the matching CV28-400-30-S flange-mounted model instead.Q: What is the standard warranty for this unit?
A: Our CH28-400-30-S gear motors come with a 12-month full warranty, covering non-human damage issues like gear wear or motor winding failure.Q: Does this model support electromagnetic brake modification?
A: Yes, we offer pre-configured brake versions (CH28-400-30-SB) for quick stop and precise positioning scenarios.Q: What shaft accessories are compatible with the 28mm output shaft?
A: It fits standard 28mm bore couplings, sprockets, and gear sets, no extra custom machining required for most industrial retrofits.
