AI Technical Summary
In the existing technology, it is difficult to simultaneously achieve both heat dissipation and mass production capability of capacitors used for noise reduction during the process of making electric motors thinner. In particular, in flat electric motors, the heat dissipation of capacitors is poor and the space is small, which affects the noise reduction effect and production efficiency of capacitors.
By designing a recessed structure on the brush holder of the motor, the main body of the capacitor is housed in the recess, and the capacitor leads are connected to the exposed portion of the terminals. The recessed structure formed on the outer surface of the brush holder enables the capacitor to be thin and has good heat dissipation. Furthermore, the method of fixing the exposed portion of the terminals to the wires improves mass production capability.
This technology enables the electric motor to be made thinner while maintaining the excellent heat dissipation and good mass production performance of the capacitor, thus solving the problems of poor heat dissipation and low production efficiency of capacitors in confined spaces.
