Document Type and Number:

WIPO Patent Application WO/2016/054862

Kind Code:

A1

Abstract:

A motor slot wedge with a sealing structure and a combination device. The structure of the motor slot wedge (1) is the following: a groove is formed in the outer wall (13, 14) of the slot wedge; thermal expansion materials (8) are arranged in the groove; the thermal expansion materials (8) are in contact with the inner wall (10, 11, 12) of an iron core tooth groove after heating expansion. The combination device includes a motor iron core with the iron core tooth groove and the motor slot wedge (1) with the sealing structure. By forming the groove in the outer wall (13, 14) of the slot wedge (1) and filling the groove with the thermal expansion materials (8), the sealing structure is formed between the slot wedge (1) and the inner wall of the tooth groove of the iron core, moisture is prevented from entering the interior of the tooth groove of the iron core and damaging the insulating structure, and paint loss after vacuum pressure impregnation could be blocked.
