Abstract:
1. A motor with centrifugal heat dissipation device, comprising: at least one shaft internally defining a hollow space and having a first end and an opposite second end; and the first and second ends being communicable with the hollow space; a centrifugal heat dissipation device including a main body having a shaft hole, a heat-absorption zone, and a heat-transfer zone; the heat-transfer zone having a radially outer side connected to the heat-absorption zone and a radially inner side connected to the shaft hole; the shaft hole axially extending through the main body, and the shaft being fitted in the shaft hole; at least one magnetic member being externally fitted around the main body of the centrifugal heat dissipation device; and a housing being internally provided with a plurality of silicon steel sheets, which are located corresponding to but spaced from the centrifugal heat dissipation device when the centrifugal heat dissipation device and the shaft are mounted in the housing; and the housing having at least one end being an open end, to which a cap is connected to close the housing, wherein the heat-absorption zone is radially outward extended from only a partial axial length of the heat-transfer zone, and defines a first transverse surface and an opposite second transverse surface; and the magnetic member being in contact with one of the first and the second transverse surface of the heat-absorption zone.
