Because the silver-copper alloy sheet of the commutator and the graphite brush are subjected to high-speed friction in the motor operation, the graphite brush is abraded in the high-speed friction, and the end of the service life of the motor is the end of the abrasion of the graphite brush of the motor. In order to effectively reduce the abrasion of the graphite electric brush, the outer circle surface of the silver-copper alloy sheet of the commutator needs to be precisely turned, so that the roundness, the runout and the roughness indexes of the outer circle surface of the silver-copper alloy sheet of the commutator are ensured, the turning depth is also strictly controlled during the precise turning processing of the outer circle surface of the silver-copper alloy sheet of the commutator, the collision and the pollution oxidation of the surface of the silver-copper alloy sheet of the commutator caused by touch are avoided, the reduction of the electric conductivity of the surface of the silver-copper alloy sheet of the commutator caused by the collision and the pollution oxidation is avoided, the accelerated abrasion of the graphite electric brush of a motor caused by the roundness, the runout and the roughness indexes is avoided, even the effective service life of the motor is seriously shortened due to sparks, however, as the silver-copper alloy sheets of the commutator are composed of a plurality of mutually separated sheets, the surface collision even the contact of adjacent sheets of the silver-copper alloy sheet of the commutator caused by The silver-copper alloy surface of the rotor assembly commutator is strictly forbidden to touch during the existence. In addition, the winding of the rotor component is made by winding enameled wires in a rotor core in a multi-layer manner to connect the commutator of the rotor component, the winding at the two ends of the iron core of the rotor component is exposed after winding, in order to avoid the motor burning accident caused by the broken wire of the enameled wire due to the damage of the surface of the winding of the rotor and the short circuit caused by the damage of the enameled wire, the rotor windings need to be strictly prevented from touching in the process of revolving and storing the rotor assembly after the winding process of the rotor assembly is finished, the surface silver-copper alloy sheet of the commutator of the rotor component is in high-speed wear conductive contact with the graphite brush of the motor when the commutator of the rotor component runs at high speed, and the end of the service life of the motor is the end of the high-speed wear of the graphite brush of the motor, so that the surface of the silver-copper alloy sheet of the commutator of the rotor component can be slightly damaged, thereby greatly increasing the wear of the graphite brush of the motor when the commutator of the rotor component runs at high speed, seriously shortening the effective service life of the motor and having serious hidden.
At present, two kinds of schemes are usually adopted, the first scheme is to adopt and punch on the plank, place the rotor subassembly pivot in downthehole turnover, nevertheless because the rotor subassembly focus on commutator and the iron core in the middle of the rotor subassembly, very easily lead to the rotor subassembly to fall in rotor subassembly turnover in-process, arouse the bruise of rotor subassembly commutator and rotor subassembly winding, this scheme can only place the individual layer in turnover and storage process in addition, unable multilayer is placed, very big use area. The second scheme is that the lattices are used in a large turnover box, so that the rotor assembly is avoided from being damaged, the large turnover box is too large in size and the occupied area is enlarged, the turnover box is additionally arranged in the inner lattices, the rotor assembly is not easy to place and take out when being placed and taken out, the production efficiency is influenced, the lattices are added at the bottom of the turnover box in a sealing state, so that impurities are easy to accumulate in the turnover box and are not easy to clean, the volume and the weight of the turnover box and the lattice scheme are too large, and the turnover scheme is too high in cost.
At present, a new technical scheme is urgently needed to solve the problems.
