Patent number: 10804761Abstract: The present disclosure provides a rotor mechanism includes a rotor core and a plurality of rotor bars. The rotor core has a plurality of insertion slots arranged along an edge of the rotor core. Each of the plurality of rotor bars has an insertion portion and two protruding portions. The insertion portions are respectively located in the plurality of insertion slots, wherein in each of the plurality of rotor bars, the two protruding portions are respectively connected to two opposite ends of the insertion portion and respectively protrude from two opposite sides of the rotor core, and the two protruding portions each has an extension direction, that has an angle with respect to an extension direction of the insertion portion, in order to clamp and fix the rotor core therebetween. In addition, the present disclosure also provides a method for manufacturing the rotor mechanism.Type: GrantFiled: December 4, 2017Date of Patent: October 13, 2020Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Yu-Hsun Wu, Ming-Mao Hsu, Yu-Yuan Chen

Patent number: 10742080Abstract: A rotor mechanism includes a plurality of rotor bars and a rotor core. The rotor bars are disposed along the edge of the rotor core. The rotor core has a plurality of magnetic flux-barrier units and at least one flux channel. Each magnetic flux-barrier unit extends from one of the rotor bars to another rotor bar. The flux channel passes through the flux-barrier units and surrounds an axis of the rotor core, wherein each magnetic flux-barrier unit is a magnetic flux barrier, and the area between the adjacent magnetic flux-barrier units and the flux channel are pathways for magnetic flux.Type: GrantFiled: December 19, 2017Date of Patent: August 11, 2020Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Ming-Mao Hsu, Wen-Yang Peng, Kuo-Lin Chiu, Chau-Shin Jang
