Why does the DC geared motor
fail to charge after a long period of use?
After being used for a long time, the DC geared motor may not be charged. The reasons for this situation can be summarized as follows.
1. The wire joints are loose or fall off, the wire sheath is damaged, and the short circuit is caused by grounding.
2. The fan pulley is too loose or slipping with oil.
3. The commutator of the motor is worn, burnt or oily, the magnetic field coil is open or shorted, the armature coil is open or shorted, the rectifiers are shorted, and the insulated carbon brush holder is grounded.
4. The regulator or throttle contacts of the DC geared motor are ablated or have dirt, the balance resistance is open, the throttle bridge line is burned, the spring tension of the throttle is weak, the air gap is too small, and the limiter voltage of the throttle Adjustment is too low, the closing voltage of the breaker is too high or the parallel coil is open.
The reasons for the DC gear motor not charging are different. We can deal with the above aspects and make a reference, which can reduce our inspection time and do the repair work in time.
