Abstract
A stator for a liquid cooling type direct drive motor comprises: annular base, silicon steel sheet, at least one metal cooling pipe, and coils. The stator is centrally provided with a rotor shaft with magnets. In the surface of the silicon steel sheet of the stator is formed a plurality of grooves, and the metal cooling pipe is continuously bent toward both sides and is positioned in the grooves of the silicon steel sheet and serves to enable coolant to circulate therein. Such arrangement simplifies the stator structure and can directly cool the silicon steel sheet, effectively and quickly lower the high temperature of the direct drive motor stator, and is compatible with the coolant passage system for an annular aluminum piece.
