Stepping driving system is also a kind of servo system, the only control way is open loop control, is not like ac servo closed-loop control, there may throw step, but mainly in choosing a stepper motor, completes the motor selection, will not lose the step in actual operation, but the cost is very low, stepping driving system is only 1/4 ~ 1/3 of the servo system. And step motor control scheme also got very fast development, such as the INAS EZS series products also USES closed-loop control, high speed performance is significantly improved, and during downtime without setting problem of the servo.
It is often used in the control for program-controlled transformation, also has the power to be used in the mechanical equipment the action transformation.
Step motors, by definition, are the motors that move in step, and a controller sends out pulse control signals. For example, when the step motor turns into a 360 degree, the controller is set to 1000 steps for 360 degrees, and the controller sends a thousand pulse signals to the controller. This type of motor is commonly used for locating accurate equipment
