The market demand increases, the stepper motor stepper motor's popularity is also slowly rising. The purpose of the step motor is very widely, because a large number of use, however, also appeared some problems and faults. In view of the present market reaction stepping motor load was shaking at work, don't start, now analysis concluded that most of them are winding end have virtual welding phenomenon. In order to solve this problem, the corresponding procedures and maintenance scheme, specific maintenance operation is as follows: 1, the winding end terminal binding wire cut, remove the insulating casing. 2, check whether there is solder in welding into the process. 3, soldering with solder iron melt, the enameled wire were scattered, check whether there is a film no ground clean, if any, using tools such as blade would shave paint film. 4, again will screw together three winding tail end, tighten, then add flux to the weld is good. 5, heat shrinkable tube. 6, binding, then back to the motor and the loading operation. 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.
