What is the cause of the failure of the DC geared motor
1. Winding faults: windings have inter-turn short-circuit faults; there are two or more contacts between the windings and the casing, resulting in ground faults.
Second, the winding connection: the group components are not connected properly; the wheel reduction motor connection line, lead length or cross-sectional area does not meet the requirements. Check the connection rules of the winding components, correct the connection rules, and correct the wrong connection components.
Third, the wire breaks: the joints of the joints are broken; the loop leads or bends are broken; the wires are broken around the wires or in the parallel branch. Check with the meter, gently shake the wire, the pointer of the meter will swing with it, it is not convenient to check the broken wire with a test lamp or an insulation resistance meter, and re-weld after checking and checking.
Fourth, the electromagnetic wire specifications: uneven thickness of the magnetic wire, one pass, one pass.
Fifth, the process of rewinding the coil: the size of the coil of the reduction motor is inconsistent; the number of turns of the coil is incorrect;
