PM stepping motor uses a permanent magnet (PM) as a rotor. NMB offers small in diameter PM stepping motors, from 3.4 mm to 55 mm diameter. Included in our line up are linear, geared and high speed PM motors.
Permanent magnet motors use permanent magenta as their main mechanical driving component, embedded in the piece itself or attached to the surface of the motor’s rotor. This method is used instead of windings like other types of motors.
