Patent number: 9006953Abstract: A stator assembly structure for an axial flux electric machine is designed. The back iron for each silicon steel disk stator is formed into a specific structure with tooth-like protrusions for allowing the same to be integrated with the disk-type stator seat, while the disk-type stator seat is made of a material suitable for casting or mold forming. A coil is mounted on the disk stator, and a stator assembly is achieved by integrating the stator, the coil and the stator seat. The stator and the disk-type stator seat of the stator assembly are manufactured by using a one-piece cast or one-piece mold forming method so as to enable the contact surfaces of the stator and the stator seat to engage with each other even more tightly, and consequently enable the heat generated from the coil to be transmitted rapidly from the disk stator to the disk-type stator seat.Type: GrantFiled: July 30, 2012Date of Patent: April 14, 2015Assignee: Industrial Technology Research InstituteInventors: Tseng-Te Wei, Shian-Hsuan Huang, Huan-Lung Gu, Shih-Ming Lo, Li-Ju Cheng
