    We must have maintenance of the stepper motor linear actuator in our daily work in order to guarantee the safety, reliability, economy and long-time running of the stepper motor linear actuator so as to meet the demand of production:

    1. Keep the motor clean and prevent oil, water and other pollution from entering the motor.
    2. Check whether the connecting terminal bolt and base fixed bolt of the motor are loose.
    3. Check the rotation of the motor fan.
    4. Check whether the motor shell is obviously heated and whether the bearings at both ends have oil leakage.
