Permanent Magnet Stepper Motors 

 
 
Permanent magnet stepper motors use a permanent magnet (PM) in the rotor and operate on the attraction or repulsion between the rotor PM and the stator electromagnets. Permanent magnet stepping motors are generally two-phase, with small torque and volume, and the step angle is generally 3.75 degrees, 7.5 degrees, 15 degrees or 18 degrees, etc. MOONS' PM stepper motors are widely applied in many innovative applications, including: computer equipment, photographic systems, optoelectronic devices, valve control, ATM equipment, CNC machine, automatic winding machines, electronic clocks and medical equipment.

What is a Permanent Magnet Stepper Motor?

The PM motor is an inner rotor type motor, and the outer surface of the cylindrical rotor is evenly distributed with N and S poles.

What are the differences between PM and VR and Hybrid stepper motors?

Comparison of performance parameters of PM motor and VR, Hybrid stepping motor.

Technical about Rated Current

Rated current of PM stepper is limited by thermal characteristics.
