    Tips: How to control the speed of hybrid stepper motor

    Since the speed of an electric stepper motor depends on the pulse frequency, the number of rotor teeth and the number of beats, the angular velocity is proportional to the pulse frequency and is synchronized with the pulse in time. Therefore, when the number of teeth of the rotor and the number of running beats are fixed, the speed control of the rotor only needs to control the pulse frequency. By controlling this aspect, the required speed can be obtained.

    In terms of permanent magnet stepper motor speed control, it should be noted that the stepping motor starts with its synchronous torque, so the starting frequency must not be too high, otherwise it will easily lose step when starting, especially with the increase of power At times, there will be a big difference between the starting frequency and the maximum operating frequency due to the increase in inertia.

    Excellent quality Nema 34 closed loop stepper motor.
    Some of the best stepper motors I’ve used. All of them are still working great. I use them in my CNC router and 3D printer. Highly recommend these stepping motors.

    Great stepper motor
    I ordered this Nema 23 closed loop stepper motor due to the higher current limit and higher torque rating to pair with my extruder on 3D printer. Everything works well as expected.
