    Tips: Daily maintenance of stepper motor linear actuator
    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.
    5. Please note if there is abnormal nose, vibration and special smell of the motor in operation.

    ATO external stepper linear actuator in this video is 2 phase 4 wire comes in Nema 23 frame size. We will show you how to use PLC connect to the hybrid stepper motor system, and control this external stepper motor linear actuator for simple forward and reverse motion by the pulse and direction command issued by PLC.

    VFD Two-Wire Control Wiring with Push Button for Forward Motor

    In this video we've guided you through how to do VFD control wiring with a self-lock push button switch to run the motor in forward direction. We've covered everything from wiring to programming and even a test run. So just watch it through and hope you'll find it informative and helpful.

    Calculation of Lead Screw and Stepper Motor

    This video introduces the calculation of stepper motor. You need to know the step angle of the stepper motor and the pitch of the lead screw as well as the number of threads and subdivisions of the driver.

    Rotation Angle Control of Stepper Motor

    The angle control principle of stepper motor is to control the number of pulse outputs of PLC.

    1. The output frequency of PLC is related to the speed of motor.

    2. Pay attention to the dip switch on the stepper motor driver, which should match the current of stepper motor, and pay attention to how many pulses control the stepper motor to rotate one circle.
