    The service life of stepper motor linear actuator refers to the cycle times that it can move and maintain stepping precision under the specified load. An operation cycle time includes the whole movement that extends and retracts to the initial position. The service life of a stepper linear actuator depends on the service life of the motor and the loss of lead screw drive. Under normal circumstances, non-captive stepper motor linear actuator can complete up to 20 million times of operation cycle while the external type motor can provide up to 25000 hours of service life. The ultimate fatigue and service life is determined by the specific application situation.

    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.
