The 57 steps, 86 steps and 110 steps of the stepper motor refer to the frame number of the stepper motor, that is, the size of the motor external dimension and installation size.
These numbers represent the number of stator teeth of the motor, and each stator tooth corresponds to a pulse signal, so the stepper motor rotates at a fixed angle for each pulse signal received, thereby achieving precise positioning and rotation control.
Stepper motors with different frame numbers have different external dimensions and installation dimensions, which are suitable for different application scenarios.
For example, a stepper motor with base number 57 is typically suitable for small, low-load applications, while a stepper motor with base number 110 is suitable for large, high-load applications.
It should be noted that the number of steps and step frequency of the stepper motor are independent parameters, the number of steps refers to the number of pulses required per revolution of the motor, and the step frequency refers to the pulse frequency of the motor rotation per second.
