    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.

    Good stepper motor for the price.
    I bought 4 of these Nema 17 stepper motors. I really like how much torque they put out and how cool and quiet they run. I would easily buy from here again.

    Good value.
    This Nema 17 stepper motor is good match and works well. It is the best packed stepper motor I have ordered. Nice wire length and works wonderful on my 3D printer. I will be ordering more.

    Great deal for quality stepper motor.
    I purchase the 3-pack of these stepper motors for my 3D printer. For my application, they work perfectly. So far I have a couple of hundred hours of prints on the Nema 17 stepper motor and they are still working great.

    Will buy this again 100%.
    Very pleased with this new Nema 17 stepper motor to replace my old one on my 3D printer. Everything looks perfect now. Just hope it will have a long life span on my printer. This is a great stepping motor and I will buy this again 100%.

    I like the price for what I got.
    Very power Nema 17 stepper motor. I need to run a geared extruder on my 3D printer, so I ordered this stepper motor. This motor has done the trick. It runs much cooler because I am not supplying it with too much power. I like the price for what I got.

    Worked perfectly for my application.
    I love this Nema 17 stepper motor. I have a project where I had to install this stepper motor on a small speaker that had manual volume control. It works great and runs cool and quiet.
