If stepper motor failure problems, or simply a structure damage, when use will inevitably lead to the operation of the motor has a poor effect, and will be used in such a state of motor, also easy to cause more serious damage to its. Is considering the aspects of the situation, so we ask you before using motor, do check the following three aspects: first, check the appearance of motor crack: before using stepper motor, need to check the overall structure of the motor, by observing the external structure of the motor, look appearance whether there is a crack, to determine whether the structure of the motor is damaged, can have very good protection effect. Second, check whether the fastening screws and parts is complete, there are many parts of the structure of the step-motor, these parts whether installation location or install state has specific requirements, any problems, will affect the function of parts. So called before using motor, pay attention to check whether the parts is complete, and determine whether parts damaged. In addition, because of the step motor at run time will produce larger vibration, such cases if the motor will not remain in a fixed state, it may bring security issues. So everyone before using motor, need to check the motor fixed situation are in good condition. 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.
