Reason for DC resistance fault of gear reduction motor

Mainly due to poor welding quality and open solder joints. Other factors related to wire materials and operations include electromagnetic wire standards, winding faults, winding connections, rewinding coil technology, and wire cracking.
1、 In terms of electromagnetic wire standards for gear reduction motors
1. The thickness of the electromagnetic wire is uneven, with one section being qualified and another section being unqualified.
2. The thickness of the electromagnetic wire is uneven, with one section being qualified and another section being unqualified.
2、 Regarding the winding problems of gear reduction motors
1. The winding of the gear reducer motor has a short circuit between turns.
2. There are two or more touches between the winding and the casing, resulting in grounding issues.
3、 Winding connection aspect

1. The winding components are not connected correctly.

2. The length or cross-sectional area of the connecting wire and lead of the gear reduction motor does not meet the requirements. Check the connection rules of the winding components, correct the faulty components according to the connection rules. Check the length, standard, and cross-sectional area of the connecting lines and leads, and correct any discrepancies that do not meet the requirements.
4、 In terms of rewinding coil technology
1. The coil size of the DC deceleration motor varies greatly.
2. The number of turns of a certain coil is incorrect
3. Uneven tension during winding
5、 Regarding wire cracking
1. There are cracks in the wires in the parallel or parallel branches.
2. Cracking at the welding joint of parallel wires.
3. Cracking of coil leads or bent wires
Using the appearance to check, quietly swing the wire, and the pointer on the surface will sway along. It is not convenient to use a test lamp or insulation resistance meter to check the cracked part of the wire. After checking, weld it from the beginning.
