Stepper motor control method; difference between stepper motor and servo motor.
Stepper motorControl method

Stepper motor is an electric motor thattranslateselectricsignalsintomechanicalrotation,

and its output rotation angle changes according to the change of the electric pulse control signal. There are several common

control methods for stepper motors, including full-step control, half-step control, and micro-step control.
Full-step control: Full-step control is themost basic control method forsteppermotors

It controls therotation of the motor by controlling the
Half-step control: Half-step control can improve the resolution of a stepper motor. In full-step control,

the motor can only rotate a fixed step angle, whereas in half-step control, the motor can rotate at half the

step angle. Specifically, when the current flows clockwise

through the first coil, the motor will rotate half a step angle forward, and when the current flows

counterclockwise through the first coil, the motor will rotate the same angle backward. Then, the current will flow clockwise

through the first coil and the second coil, causing the motor to rotate forward again by half a step angle. By alternately

controlling the direction of the current, more precise control can be achieved, improving the accuracy and resolution of the stepper motor.
