The invention relates to a feeding device of a motor stator end cover. Supporting blocks with the upper outlines matched with the shape of a cover cavity of the stator end cover to be carried are arranged at the discharging end of a horizontally-arranged conveying belt, the height of the upper end face of each supporting block is smaller than or equal to the height of the belt face of the conveying belt, and a fence is arranged at the front end of the discharging end of the conveying belt and placed above the supporting blocks. The distance from the fence to the belt face of the conveying belt is smaller than the axial dimension of the stator end cover. The lower portion of each supporting block is connected with the suspension end of a cantilever rod, and the other end of the cantilever rod is connected with a moving mechanism. The moving mechanism drives the supporting blocks to be placed at a material receiving position at the front end of the discharging end of the conveying belt and material supplying positions vertically corresponding to pressing dies of a pressing device respectively, the supporting blocks and the moving mechanism enable the stator end cover to be supported and moved into a die cavity of a pressing base of the pressing device, and the fence achieves the limiting function and the clamping function on the stator end cover so that the stator end cover cannot drop when being conveyed onto the supporting blocks. By means of the feeding device of the stator end cover, automatic feeding of the stator end cover is achieved, and operation is reliable.
