Stepper motor manufacturers subdivide stepper motors for you


The subdivision technology of a stepper motor is essentially an electronic damping technology. Its main purpose is to reduce or eliminate the low frequency vibration of a stepper motor. Improving the operation accuracy of the motor is only an incidental function of the subdivision technology. For example, for a two-phase hybrid stepping motor with a step angle of 1.8 °? If the number of subdivisions of the subdivision driver is set to 4, then the motor's operating resolution is 0.45 ° per pulse. Can the accuracy of the motor reach or Close to 0.45 °, it also depends on other factors such as the precision of the subdivision current control of the subdivision driver. The precision of the subdivision driver of different stepper motor manufacturers may vary greatly; the greater the number of subdivisions, the more difficult it is to control the accuracy.

The number of subdivisions of the stepper motor driver.
There are three general subdivision methods
N to the power of 1, 2, such as 2, 4, 8, 16, 32, 64, 128, 256 subdivisions,
Integer multiples of 2, 5 such as 5, 10, 20, 25, 40, 50, 100, 200 subdivisions,
Integer multiples of 3 and 3, such as 3, 6, 9, 12, 24, 48 subdivision.

The information found is hope to help you. The stepping motor driver divides the driving current into multiple levels and corresponds to different speeds or torques, so that the motor runs more stable.
