In another embodiment, the winding heat sink part is connected to the heat sink fins 131, and the gap between the two is filled with a heat conducting medium, that is, the winding heat sink part is located outside the housing 100 through the heat sink fins 131. For example, the winding heat dissipation part is inserted into the heat dissipation fins 131, and heat is dissipated through the heat dissipation fins 131.
As shown in fig. 1 and fig. 3, the heat-dissipating axial motor further includes a protective cover 140, and the protective cover 140 is fixed to a side of the first end cap 110 facing away from the housing 130, so that the cooling fan 500 is located in a receiving cavity formed by the protective cover 140 and the first end cap 110.

In summary, the core heat absorbing portion of the core heat sink 420 directly contacts the core 210, absorbs heat generated by the core 210, and then dissipates heat through the core heat dissipating portion located outside the housing 100. The iron core heat sink 420 has a simple structure, so that a heat conduction path is short, bending is not needed, the complexity of a manufacturing process is reduced, and the reduction of heat conduction performance is avoided. In addition, the cooling fan 500 acts on the iron core heat dissipation portion, thereby further improving the heat dissipation performance.
