Stepper motor is the general machinery equipment manufacturing machinery parts, mainly with a driver. In use process must pay attention to the speed for effective control, avoid the out-of-step and overshoot phenomenon. To understand more deeply the stepper motor can detect the stepper motor step and overshoot phenomenon is mainly occurred at the time of start and stop, so in the two time periods must be prepared. In some simple control or the requirements of low cost of motion control system, often with stepper motor actuators. Stepper motor in the applications of the biggest advantage is: can use the way of open loop without feedback can to control the position and speed. Due to the load position has no feedback for control circuit, stepper motor must be correct response field changes each time. Incorrect if the excitation frequency, the motor will not be able to move to a new location, so the actual load position relative to the location of the controller is expected there will be a permanent error, namely the out-of-step phenomenon or overshoot phenomenon. As a result, the stepper motor open-loop control system, how to prevent out-of-step and overshoot phenomenon is the key of the system can run normally. Step out of step motor and overshoot phenomenon appears when starting and stopping, respectively. The stepper motor starts, if running speed is less than the limit start frequency, can be directly according to the requirements of speed, otherwise you must have a process to accelerate. In general, the limit of the system startup frequency is lower, and the requirements of high speed. If the system to the requirements of the speed start directly, because the speed is more than the limit of the stepper motor start frequency and cannot be normal boot, light will probably be out of step, or simply cannot start, have blocked. When the stepper motor to stop operation, there must be a slow process. System running start later, if at the end of the object to stop immediately, when the inertia effect due to the system, the motor rotor turn equilibrium position. If the load inertia is very big, can make the stepping motor rotor to the equilibrium position close to the end of the next equilibrium position, and stop at the location, thus generating overshoot. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
