Even good quality of stepper motor, are also likely to be down in the use, so for many users of the motor, all need to master these motor repair methods, so that the motor failure problem, through the optimization of the maintenance work, timely find out the cause of the problem and solving, timely return to normal operation of motor and using: maintenance method one: intuitive method. So-called intuitive method, in fact, the visual method, specifically require everyone to use the eyes and other senses to find stepper motor fault location, through the observation to find out the cause of the problem of the motor, so as to timely troubleshooting. Maintenance method 2: multimeter method. Such maintenance method of stepping motor, need to use the multimeter this tool, by using a multimeter to measure the resistance of the motor winding, work voltage, current, and will measure value compared with the normal to determine the cause of the problem. Maintenance methods: shaking table method. In this way maintenance step motor, also need to use tools, specifically to be shaking table is used to measure the insulation indicators of the motor, and then by normal value with the measured value is compared to determine the cause of the problem. In addition, users can also use waveform diagram method, at the same time with the oscilloscope observation stepper motor of the main circuit waveform, and based on the waveform analysis to judge the fault of the machine. 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.
