Tips: Basic principle of stepper motor linear actuator
The stepper motor linear actuator is meshed with a screw and nut, so as to prevent the relative rotation of the screw nut so that the screw will have axial movement. There are two ways to achieve this transformation. The first is to build a rotor with inner screw thread in the stepper motor so as to achieve the linear motion through the mesh of internal thread and the screw. The second is to use the screw as the output shaft of the motor. A linear motion is achieved by meshing the external drive nut and screw. It simplifies the design greatly so that precise linear motion can be carried out in many application areas without installing external mechanical linkage device.

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.

1.8 degree stepper motor teardown & construction display

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.
