How to choose a stepper motor driver for a stepper motor - 推酷

The operation of the stepper motor needs to be driven by a pulse-distributed power type electronic device. This device is a stepper motor driver, a good stepper motor, without a driver drive, it cannot be operated, and only the matching motor In order to get the best running state of the motor, how to choose a driver that can improve the performance of the motor?

First, select the appropriate driver according to the rated current of the stepping motor. Any stepping motor has its own rated current. The maximum current of the matching driver should not be lower than the rated current of the motor. The stepping motor driver produced by Shanshe Motor has the function of current subdivision, that is, the current of the driver can be set according to the rated current of different motors. The same driver can be equipped with motors of different currents, as long as the rated current of the motor is less than The current when the driver is adjusted to the maximum can be used, otherwise the motor may be burnt. Second, according to the required step angle to select the drive stepper motor on the market is generally 1.8 °, 1.2 ° and 0.72 ° step angle, but because the customer's accuracy requirements for the motor is higher, the step angle There are also different requirements. In order to meet the needs of customers, the motor manufacturers are subdivided by the subdivision of the drive. Yamashita motor drive has half-step and full-step, binary and hexadecimal and full subdivision, customers can choose different subdivision drivers according to the needs of their products. 3. According to the AC voltage and voltage provided by the power supply, there are AC voltage and DC voltage. The stepper motor driver has a rated voltage. When selecting the driver, the motor driver must be selected within the voltage range that the power supply can provide. If the rated voltage of the selected drive is too low, the voltage supplied to the drive by the power supply is higher than the rated voltage of the drive, and the drive is easily burned out. Yamato Electric provides AC and DC voltage drivers for customers with different needs. 4. Select the driver according to the voltage required to reach a certain speed when the stepping motor is running.

The above four points are the most important four aspects of selecting a drive, and I hope to help those who need to choose a stepper motor driver.
