2 phase 4V, 0.95A Nema 17 Stepper Motor Linear Actuator with higher performance and lower cost. To meet the needs of a wide range of linear motion applications, two stepper motor linear actuator styles are available:
Non-captive shaft has a threaded shaft that extends through the motor and moves axially as the motor rotates.
External shaft has a rotating screw, integral to the motor's rotor, that moves the nut axially along the threaded shaft.

Tips: Screw Pitch of stepper motor linear actuator
The step length of linear screw stepper motor depends on the step angle and pitch between the interoperable internal thread nut and lead screw. The steep-pitch thread produces larger step length than the small pitch thread. However, for a given stepping rate, small pitch thread can provide greater propulsive force. When the motor is out of power, steep-pitch thread can easily be driven in the opposite direction while the small pitch thread cannot. There must be a certain degree of freedom the rotor and the screw in order to guarantee the high work efficiency, which requires a certain gap between them, about 0.03 to 0.08 mm axial gap (also called reverse gap). Generally, the larger the helical pitch is, the larger the gap is.

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.

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.

In the case of non-overload, the speed and stop position of the motor only depend on the frequency and pulse number of the pulse signal, and are not affected by the load change. That is, when a pulse signal is added to the motor, the motor rotates through a step angle. The existence of this linear relationship, coupled with the characteristics of the stepper motor having only periodic errors and no cumulative errors. This makes it very simple to use stepper motors to control the speed, position and other control fields.
