AI Technical Summary
The existing commutation mechanism of three-phase motors has a complex structure, many parts, and high assembly costs, which is not conducive to the use of cables for commutation.
A phase-switching mechanism was designed, including a plug housing and a phase-switching seat. Through structures such as limiting bosses, limiting components and sliders, the phase-switching seat is limited and rotated on the plug housing, which simplifies the phase-switching operation and reduces the number of parts.
The design achieves a lightweight component structure, facilitating assembly, improving the convenience and stability of phase switching, and reducing assembly costs.
