This invention proposes a structure,
assembly method, and a laminated pole
synchronous motor for improving the heat dissipation capacity of the damping strip in a laminated pole
synchronous motor. It belongs to the field of laminated pole synchronous motors. The invention solves the problem of how to effectively improve the heat dissipation capacity of the damping strip in a laminated pole
synchronous motor. The heat dissipation structure consists of multi-layered fins welded to the damping strip of the laminated pole synchronous motor. A
graphene coating is sprayed onto the fins and damping strip. The damping strip has a hollow structure filled with
phase change material. One end of the damping strip is fixed to a damping ring, and the other end is connected to the pole core. Heat dissipation fins are provided at the bottom of the damping ring. This invention employs a composite heat dissipation
system of "
internal phase change flow
heat transfer + fins + damping ring heat dissipation fins": internally, the
phase change cycle of the
phase change material promotes uniform
heat distribution; externally, the heat dissipation fins on the surface of the damping strip and the integrated heat dissipation fins of the damping ring form a three-dimensional heat dissipation network, significantly accelerating the transfer of heat from the damping winding to the external environment.
