Patent ID: 8760018

Claim:
A motor stator with heat dissipation structure, comprising: a silicon steel plate assembly including a plurality of stacked silicon steel plates; each of the silicon steel plates including a plurality of radially outward extended magnetic poles, and the magnetic poles of the stacked silicon steel plates together defining a plurality of magnetic-pole columns with a space formed between any two adjacent magnetic-pole columns; and each of the magnetic-pole columns having at least one winding wound thereon; a covering being a heat-conducting plastic material and filled into the spaces between the adjacent magnetic-pole columns and covered over the silicon steel plate assembly and the windings; a plurality of heat pipes being arranged in the spaces and extended into the covering filled in the spaces a fan circuit board connected to one of two axially opposite sides of the silicon steel plate assembly; and wherein the heat pipes respectively have an end extended through the covering to connect to the fan circuit board and a heat-dissipating end extending outside the covering to dissipate heat into ambient air.
