1, the way of control is different
Stepper motor: The angle of rotation is controlled by the number of control pulses, one pulse corresponding to one step angle.
Servo motor: Control the rotation angle by controlling the length of the pulse time.Spin Motors Manufacturers
2, the workflow is different
Stepper motor: The workflow requires two pulses for stepper motor operation: signal pulse and direction pulse.
Servo motor: The working process is a power connection switch, and then connected to the servo motor.
