The advantage of stepper motor
- Oct 31, 2018 -

1、 The angle of rotation of the stepper motor is proportional to the number of pulses.

2、 The stepper motor has the maximum torque when it stops rotating (when the winding is energized).

3、 Since the accuracy of each step is 3-5, and the error of one step is not accumulated to the next step, there is better positional accuracy and repeatability of motion.

4、 Excellent start and stop and reverse response.

5、 Since there is no brush and the reliability is high, the life of the stepper motor depends only on the life of the bearing.

6、 The response of the stepper motor is determined only by the digital input pulse, so open loop control can be used, which makes the structure of the stepper motor simpler and lower in control cost.

7、 Simply connecting the load directly to the shaft of the stepper motor can also be rotated at a very low speed.

Since the speed is proportional to the pulse frequency, there is a wide range of speeds.
