Cooling structure of a rotor for an axial flux motor
A rotator for an axial flux motor contains: a core and two permanent magnets located on two end surfaces of the core. The core includes two circular grooves defined on the two end surfaces of the core, two flanges formed on two centers of the two end surfaces of the core, and a peripheral fence formed on an outer wall of the core, multiple passing slots radially formed on the two end surfaces of the core and passing through the core, and multiple through orifices defined around the peripheral fence and communicated with the multiple passing slots. A respective one permanent magnet of the two permanent magnets is circular and includes multiple N poles and multiple S poles. The two permanent magnets are fitted in the two circular grooves of the core and are magnetically attracted on the core.
1 . A cooling structure of a rotor for an axial flux motor, comprising:
a core and two permanent magnets located on two end surfaces of the core;
wherein the core includes two circular grooves defined on the two end surfaces of the core, two flanges formed on centers of the two end surfaces of the core, and a peripheral fence formed on an outer wall of the core;
wherein multiple passing slots pass through the core between the two flanges and the peripheral fence;
wherein a length of the multiple passing slots is defined between the two flanges and the peripheral fence;
wherein the multiple passing slots extend through the core;
wherein multiple through holes are defined on the peripheral fence and communicate with the multiple passing slots;
wherein each of the two permanent magnets is circular and includes multiple N poles and multiple S poles;
wherein the two permanent magnets are fitted into the two circular grooves on two sides of the core and are magnetically attracted to the core;
wherein the annularly arranged passing slots on the two side surfaces of the core are covered by the two permanent magnets such that each passing slot forms a channel.
