FAQ
1.What is the typical step angle in PM stepper motors?
PM stepper motors generally have step angles ranging from 7.5 to 18 degrees per step, depending on the number of rotor poles and stator phases.
2.Can permanent magnet stepper motors be used with microcontrollers?
Yes, PM stepper motors can be easily controlled by microcontrollers via stepper drivers using pulse signals for speed and direction control in embedded applications.
3.Can PM stepper motors be customized for special use?
Yes. Manufacturers can customize shaft dimensions, mounting options, wiring, step angles, and voltages to suit specific mechanical or electrical system requirements.
4.Can PM stepper motors be waterproof or sealed?
Yes. Special housings with IP ratings protect against water, dust, or oil for harsh industrial or outdoor environments.
5.Are PM stepper motors compatible with gearboxes?
Yes. Gearboxes are often added to increase torque and reduce step angle, improving control in high-load or slow-speed applications.
6.How long do PM stepper motors typically last?
With no brushes and minimal wear components, PM stepper motors can last thousands of hours under normal operating conditions with proper cooling and load management.
