Stator auxiliary slot structure and stator

Abstract

The auxiliary slot structure of the stator optimizes the auxiliary slot arranged on one end of the stator pole tooth facing the air gap, and particularly divides the auxiliary slot into a slot opening formed on the tooth crown surface of the tooth body of the pole tooth facing the air gap, a first slot area in the tooth body, and a second slot area between the slot opening and the first slot area, wherein the maximum width of the first slot area is greater than the maximum width of the second slot area, and the maximum width of the slot opening is less than or equal to the maximum width of the second slot area. Through the structure that the slot opening is smaller than the maximum slot width of the first slot area, the possibility of the glue existing in the auxiliary slot after filling is reduced.
