Patent number: 10141818Abstract: A winding frame structure for an automation winding machine to conveniently produce the windings of a motor includes two barrier plates, four ceramic heat conductive structures with high heat conductivity, and special-structured grooves. The ceramic heat conductive structures can significantly enlarge the heat dissipation area of the windings. The heat generated by the windings can be swiftly transmitted firstly to the ceramic heat conductive structures, then to the stator inside a space formed by assembling the four ceramic heat conductive structures, and finally to a motor casing. An air-cooling or water-cooling apparatus is introduced to swiftly dissipate the heat at the motor casing. Provided by the winding frame structure, the temperature difference between the inside and the outside of the winding frame structure can be reduced, the heat dissipation process can be more efficiently, and the winding arrangement of the windings for motors can be conveniently performed.Type: GrantFiled: December 18, 2015Date of Patent: November 27, 2018Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Jih-Yang Chang, Han-Ping Yang, Chau-Shin Jang, Shin-Tien Yeh
