    Tips: How to solve the noise problem for Nema 14 micro stepper motor?

    1. If stator and rotor of the Nema 14 micro stepper motor collide with each other and make a harsh chatter noise, it should be a bearing problem. Replace with new bearings.
    2. If you hear the sound of grumbling noise, it means that the bearing is seriously short of oil. Clean the bearings and add oil.
    3. If the noise of Nema 14 micro stepper motor is extremely loud, it is possible due to phase failure of the motor, or a phase of the switch and contactor contacts is not connected. Turn off the power first and then switch on to see if it can start normally again. If it fails to start, then one phase of the fuse may be broken.
    4. If fan blade hits the shell or there is debris, it will produce a noise similar to the impact. Remove the debris near the blades of Nema 14 micro stepper motor.
