Abstract
A brushless motor with an internal integrated heat dissipation module thereof is provided. The brushless motor includes a stator including at least one recess to receive a corresponding heat dissipation module therein, and an outer rotor, the heat dissipation module sliding in the corresponding recess to contract to the bottom of the recess; an ejection element arranged in the recess for pushing the heat dissipation module outwards from the recess; two to four temperature sensors integrated in the heat dissipation module; the outer rotor including an annular pressing plate formed at a top thereof to bind and compress a wire harness at the end of a coil winding; an interior cavity inside the stator providing an annular baffle for dividing the cavity into inner and outer parts, and sealing the internal cavity, thereby air only flowing, through the external part near the outer side of the annular baffle.
