Tips: How to select the protection form for stepper motor linear actuator
It is necessary to select the appropriate protection form for stepper motor linear actuator according to different environment, in order to prevent the damage to the stepper motor linear actuator caused by the surrounding environment and substances or the disaster caused by the stepper motor failure. The protection forms of the stepper motor are open type, protective type, explosion proof type and closed type. We should follow the following principles in selection.

The open type stepper motor can only be used in dry and clean environment.
The protective stepper motor linear actuator is suitable for dry environment with no dust, explosive and corrosive gas. This kind of stepper motor linear actuator can be selected in such circumstance because they are well-ventilated.
The explosion proof type stepper motor linear actuator can be applied in the environment of explosion danger (such as in the pit of gassy mine).
The closed type stepper motor linear actuator can be divided into self-cooled type, non self-cooled type and sealed type. The former two type can be used in wet environment with corrosive dust and weathering. The latter is applied in the equipment dipped in water (such as submerged pump).

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.
