Frequently Asked Questions
What is a PM stepper motor?
It is a brushless DC motor that rotates in fixed steps using a permanent magnet rotor, ideal for cost-effective positioning.
What is the typical step angle for these motors?
These motors usually feature a 7.5° or 15° step angle, providing stable positioning accuracy for common applications.
Does the motor hold its position when power is off?
Yes, it features detent torque generated by the permanent magnet, which helps maintain position without power.
How can I reverse the motor's rotation?
Rotation can be reversed by changing the driving phase sequence or toggling the DIR signal on your motor driver.
What are the main applications for these motors?
They are widely used in printers, HVAC valves, medical devices, automotive actuators, and small consumer electronics.
What voltages are commonly available?
Standard models are available in 5V, 12V, and 24V configurations to suit various power requirements.
