Stepper motor structure of any part of the problem, will affect the running effect and function of it, so everyone in the process of using motor, very need to keep protection of various structural parts of the motor, such as guarantee drives well ventilated, protect motor shell from external shocks, don't put metal debris and dust into the motor drives the plate, and so on. Among them, asking people in the use of stepper motor, don't wait for metal debris and dust fall into motor drives the plate, the key reason is that the motor drive board is not seal structure, its structure is an open state, once the metal debris and dust fall into to the structural part, is easy to attach on the driver board in the related parts, the problems easy to cause a short circuit. Once stepping motor short circuit occurs, normal operation of the will, nature will not function properly, you can't normal use. So, in order to guarantee the stability of the stepping motor to run, reliable function, normal use for a long time, requires that everyone in the use of the motor, don't put metal debris and dust into the motor driver board, to protect the circuit on the driver board through, to do a good job in security in terms of operation and function of the motor. 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.
