Abstract
The invention discloses an insulating frame, and relates to the technical field of motors. The insulating frame includes an outer wall and an inner wall that surround each other. The outer wall and the inner wall are connected through multiple coiling parts. The inner wall is formed by multiple inner baffle plates arranged at intervals. The number of the inner baffle plates is equal to that of the coiling parts, and the inner baffle plates correspond to the coiling parts one by one. The bottom on the inner side of each of two ends of each inner baffle plate is equipped with a groove paper buckle, a groove paper clamping groove is disposed between each groove paper buckle and one corresponding inner baffle plate, and the bottom of each of the two ends of each inner baffle plate is also equipped with a groove structure that is communicated with the corresponding groove paper clamping groove. The invention also discloses a motor stator and a motor including the insulating frame The bottom walls on the two ends of each inner baffle plate are additionally provided with the groove structures that are communicated with the groove paper clamping grooves to enable the space of the groove paper clamping grooves to be increased, so groove paper will not be drawn into an iron core along with coiling pins during coiling. Therefore, the cooperation range between the groove paper and the insulating frame is increased, the tighter contact performance is exhibited, hidden troubles of causing the groove paper to be drawn into the iron core after coiling are effectively reduced, and groove winding is less likely to occur.
