Tips: Driving power of stepper motor linear actuator
The operating characteristics of stepper motor linear actuator is closely related with matching driving power. The driving power is to provide the pulse sequence that is sent by numerical control device automatically for each phrase winding according to the required power distribution mode so as to drive the motor rotation. Its control circuit consists of a distributor and a power amplifier.

A series of continuous pulses sent by the numerical control device are allocated to each winding of the stepper motor in a certain order through the distributor, so that each phase winding can be connected to and cut off according to the predetermined control mode. Therefore, we need to determine the working state of the distributor according to the electrified mode of the stepper motor when designing the distributor.
The pulsing signal power of the distributor output is small while the pulse current required by the winding of the stepper motor reaches a few amperes. So the impulse sent by the distributor must be magnified to control the running of the stepper motor.

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.
