Tips: Classification of stepper motor linear actuator
The stepper motor linear actuator can roughly be divided into two types according to the principle of the propulsive force in electromagnetic field, variable reluctance and mixed type. The former has the advantages of simple structure and low cost and its shortcoming is that the magnetic force is small, asymmetric and the torque fluctuates greatly. The latter is added with permanent magnet on the basis of the former. Therefore, even in the case of power failure, the permanent magnet can also generate a certain torque and can continue to run a certain distance in a straight line. The existence of permanent magnet can form a larger propulsive force in unit volume compared with reluctance. It can easily complete the micro-step control and has less dependence on the parameter in its control distance. The partitioning technique is usually used in the hybrid motor order to improve the smoothness of the linear motion and reduce the fluctuation caused by propulsive force.

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.
