The utility model discloses a graphite pole plate impregnation cage relates to mechanical engineering technical field, is used for separating multiple graphite pole plate and carries out impregnation, including main frame, the side of main frame along length direction is provided with baffle, and the other side of main frame along length direction is provided with the opening, so that graphite pole plate can be inserted to the inside from the opening side to main frame and is positioned under the action of baffle, the top of main frame is provided with the partition, and the bottom of main frame is connected with positioning piece, and the positioning piece is connected with partition and forms a plurality of installation sites for installing graphite pole plate, so that when graphite pole plate assembly is to main frame, graphite pole plate is installed in the installation site, so that multiple graphite pole plate can be separated in main frame.

The invention provides an iron core punching sheet, a rotor assembly and a motor. The iron core punching sheet comprises an annular body and a plurality of tooth yokes, and the tooth yokes are evenly arranged on the outer wall or the inner wall of the body in the circumferential direction of the body. A wire slot is formed between every two adjacent tooth yokes and is used for accommodating a winding; one end of the tooth root part of the tooth yoke is arranged on the body, and the other end of the tooth root part of the tooth yoke is connected with the tooth tip part of the tooth yoke; the tooth top parts are symmetrically arranged in the radial direction of the body and are provided with bulges in the circumferential direction of the body; the tooth tip part comprises a first structural body, and the plane where the first structural body is located and the plane where the body is located are arranged in a crossed mode. According to the iron core, the tooth tip parts of the tooth yokes and the body are arranged in a crossed manner, so that the axial end of the winding is limited, an insulation structure does not need to be additionally arranged, and the phenomenon that an insulation structure on a traditional iron core is prone to damage is avoided.
