Abstract

A liquid cooling type direct driving motor stator comprises an annular base, a silicon steel plate, at least a cooling metal tube and coils, and in a center of the liquid cooling type direct driving motor stator is disposed a rotor shaft having a magnet. A plurality of receiving grooves is defined in a surface of the silicon steel plate; the cooling metal tube is extended to the receiving groove of the silicon steel plate and is provided for the circulation of the cooling fluid. Such arrangements not only simplify the components and cool the silicon steel plate directly, but also reduce the high temperature of the direct driving motor stator, and further cooperate with the conventional channel liquid cooling system of the annular aluminum housing.
