Tips: What do you need to know about stepper motor?

1. The stepper motor is used in low-speed occasions-the speed does not exceed 1000 revolutions per minute, and it is best to use between 150-450 RPM, which is most beneficial to the optimized operation and function of the motor. If you want to achieve this kind of control in the use of the motor, you can make the motor work here through the deceleration device, and keep it in this state. When the motor is used, it can achieve high work efficiency, the noise generated is also very low, and the overall performance is relatively good.
2. The stepping motor is best not to use the full-step state, because the vibration generated during operation will be relatively large. Once the motor's vibration is large, it may cause noise pollution and aggravate the loss of related parts of the motor in daily use, so that the running performance of the motor will gradually deteriorate, and the service life will be shortened to a certain extent.
