Stepper Motors
PM (Permanent Magnet)
These stepper motors use a permanent magnet in the rotor. They are generally two-phase motors, with limited torque levels, reduced dimensions and the step angle can be 3.75° – 7.5° – 15°- 18°, etc.
MOONS’ PM stepper motors are widely used in many innovative applications, among which IT devices, photographic systems, optoelectronic devices, valve control, ATMs, CNC machines, automatic winders, electronic clocks and medical equipment.
Differences between PM and hybrid steppers
| PM | Hybrid |
| Cheapest | More expensive |
| Simple design | More complex structure |
| Step angle: da 3°a 30° | Step angle: 1.8°, 1,2°, 0.9°, 0.45° |
| Good torque at low speeds, significant drop at high speeds | High torque – More torque available at the same speeds |
| Ferrite magnets | NdFeB Magnets |
1 – PM Stepper Motors, how they are made
The permanent magnet motor (PM) has a stator structure similar to that of the stepper motor at variable reluctance. The rotor is made up of permanent magnet poles in steel, at high retention in cylindric shape. The concentric windings on the poles that are diametrically opposite are connected in series to form a two-phase winding on the stator.
2 – Permanent Magnet Linear actuators
In addition to rotational stepper motors, MOONS’ proposes a range of permanent magnet linear actuators. These products are available in “non captive” and “captive” versions and have very reduced dimensions; their diametre goes from 20 mm to 35 mm. Do you want to know more? .
3 – Permanent Magnet Gear motors
Variants of permanent magnet motors with a gear box already integrated are available, that allow us to reach a very reduced, step angle that translates into greater precision and fluidity in movement. Do you want to know more?
