1. On earth to repair the armature winding flux is usually in the armature slot section, or end of winding, at this moment if you can troubleshoot, will pass to repair. If it is in the interior of the tank, cannot be ruled out fault, just get rid of this part of the winding, which referred to 'jump connection' as shown in figure 717. Will pass to the winding head off two leads, and is connected by a line will be two commutator segment, in lieu of coil, make winding is still a closed loop. 2. Fault repair by check to make sure the rotor winding is the presence of short circuit, is this part of the winding can be separated from the whole winding, as shown in figure 718. The defective coil at the commutator two heads off with a wire to commutation of two pieces together, instead of the original coil, will short-circuit coil cut open at the same time. Jump connection short-circuit coil repair, also could damage the other coil around, so the operation should pay attention to the surrounding coil. Jumper method can make the stepper motor work, but will degrade the performance of the stepper motor, the repair method is temporary measures. 3. Open-circuit fault repair by checking that determine the stepper motor winding is open circuit element exists, and is the cause of open circuit due to poor and commutator welding or virtual welding, as long as the solder joints welded again good, if the open circuit to produce step motor groove, when will it connected is impossible, for the sake of temporary works, just put the commutation of circuit components corresponding to two pieces of short connected, as shown in figure 719. The armature winding formation of the two branch is then on, though this will cause imbalance of winding, but it will also be able to work. The above three methods of repair. Are temporary measures, the use of can only solve a problem, because this kind of repair method cannot solve the fault components repair of stepper motor, so the operation of the stepping motor is not balanced, running performance is poor, but it still can use. Thoroughly the stepper motor repaired will rewind repairing. 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.
