Tips: The stepper motor must match the corresponding stepper driver to work

The stepper motor cannot be installed separately in the corresponding equipment, it must be matched with the corresponding stepper driver. The stepper motor needs to cooperate with the driver to receive the digital signal of the CPU, PLC and other controllers.

Stepper motor driver is an actuator that converts electrical pulses into angular displacement. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation and positioning. The subdivision technology is essentially an electronic damping technology, and improving the running accuracy of the motor is only an incidental function, and the main purpose is to reduce or eliminate the low-frequency vibration of the motor.

For example, for a two phase hybrid bipolar stepper motor with a step angle of 1.8°, if the subdivision number of the subdivision driver is set to 4, the motor's operating resolution is 0.45° per pulse. However, whether the accuracy of the motor can reach or connect to 0.45° depends on the subdivision current control precision of the subdivision driver and some other factors.

To reduce the working noise of the stepper motor, the subdivision driver is usually chosen, especially when the motor is working at a low speed, the vibration and noise of the motor will be more obvious. It is recommended to use a subdivision driver to alleviate this situation and promote the improvement of the vibration and noise of the motor at low speeds.
