In addition to the power circuit and motor windings, the fault is mostly caused by the abnormality of the motor's starting circuit. Electric fans, exhaust fans, washing machines and other motors generally use capacitors to start operation; while refrigerators, freezers, etc., motors mostly use resistance split-phase start-up operations. Once the capacitor or split-phase resistance in the starting circuit is damaged, the motor will not operate normally. Check the motor fault after troubleshooting the starting circuit fault.
If the starting circuit is normal, it may be a partial short circuit or open circuit in the internal windings of the motor, which can be judged by measuring the resistance value of each winding with a multimeter R×1 gear. For example, the resistance value of the starting winding is about 23Ω and the resistance value of the running winding is about 10Ω under normal conditions. The normal resistance value of the starting and running series windings should be the sum of the two.
This is the introduction to the maintenance of the DC geared motor that does not start after the power is turned on. If you encounter operational problems in this area in the future operation and use, you can carry out specific operation practices based on the content explained in the article to avoid causing greater loss.
