The main reason is that the welding quality is poor and the solder joints are open.In addition, the wire material and operation also have the following factors such as the standard of the electromagnetic wire, the winding fault, the winding connection, the rewinding coil technology, and the cracking of the wire.
1. Standard aspects of gear reducer motor electromagnetic wire
1. The thickness of the electromagnetic wire is uneven, one section is qualified, and some section is unqualified. 2. The thickness of the electromagnetic wire is uneven, one section is qualified, and some section is unqualified.
Second, gear reducer motor winding faults
1. The gear reducer motor (gear reducer motor) winding has an inter-turn short circuit fault. 2. There are two or more contacts between the winding and the casing, and a grounding fault occurs.
3. Winding connection
1. The winding components are not connected correctly. 2. The connecting wire, lead wire length or cross-sectional area of the geared motor do not meet the requirements.Check the connection rules of the winding components, correct the connection rules, and correct the wrong components.Check the connection line, lead length and size, and cross-sectional area, and correct those that do not meet the requirements.
4. Technical aspects of rewinding coil
1. The coil size of the DC geared motor is inconsistent. 2. The number of turns of a certain coil is wrong 3. Uneven tension when winding
Five, wire cracking
1. There are cracks in parallel winding wires or parallel branch wires. 2. The welding part of the parallel wire is cracked. 3. Cracking of coil leads or wires at bends
Check with a meter, gently shake the wire, and the pointer on the meter will swing accordingly. It is not convenient to check the cracks of the wire with a test lamp or an insulation resistance meter. After checking, re-weld it.
