Tips: Different types of stepper motors

Stepper motors can be divided into reactive stepper motors, permanent magnetic stepper motors and hybrid stepper motors according to their structure.

• Reactive stepper motor
  It is also called induction type, hysteresis type or reluctance type stepper motor. Its stator and rotor are made of soft magnetic materials. The large magnetic poles on the stator are equipped with multi-phase excitation windings. Small teeth and slots are evenly distributed around the stator and rotor. After energization, the change of magnetic permeability can generate rotation. The step angle is small, the internal damping of the motor without positioning torque is small when the power is off, the single-step operation has a longer oscillation time and the start-up and operation frequency are higher.
• Permanent magnet stepper motor
  Under normal circumstances, it is made of permanent magnet material for the motor rotor, and the stator is made of soft magnetic material. There are multi-phase excitation windings on the stator. There are no small teeth and slots around the stator and the rotor. After energization, the permanent magnet and the stator current magnetic field can interact with each other. This action produces torque. Most of them are 2 phase or 4 phase, with small output torque, large step angle, certain holding torque when power is off, and low starting and running frequency.
• Hybrid stepping motor
  It is also called permanent magnet induction type stepper motor, which combines the advantages of permanent magnet type and induction type. Its stator is no different from a four phase induction stepper motor, but the rotor structure is still more complicated. It is a nice stepper motor with higher starting and running frequency for CNC machine and robot arm.
