Gear motor & # 8203; Geared motor dc resistance fault reason mainly is the poor welding quality, welding spot is open. Another wire materials, operations, and the following electromagnetic wire standard, winding fault, winding connection, heavy coil craft, traverse cracking and other reasons. A, the gear reduction motor electromagnetic wire standard 1. Electromagnetic wire uneven thickness, a qualified, a certain period of unqualified. Second, the gear reduction motor winding faults are 1. Geared motor winding interturn short circuit fault. 2. Winding has two or more than two touch with chassis, ground fault occurs. Third, winding connection 1. Winding component cohesion is not correct. 2. Geared motor connecting wire, wire length or area is not in conformity with the requirements. Check the winding element join rules, will join rules, will join and correct wrong components. Check the connecting line length and standard, lead and cross-sectional area, is not in conformity with the requirements will be corrected. Four, 1 heavy coil technology. Dc gear motor coil dimension intrusive inconsistent. 2. A coil circle number 3. Uneven tension during winding five 1, cracking of wire. And around the wire or wires in parallel branch have craze. 2. Parallel wire welding crack. 3. Coil lead wire cracking in appearance or bend to check the, quietly to sway, conductor appearance pointer will follow, lead by trial lamp or insulation resistance meter cracking to check the not convenient, check out after welding is good from the start.
