Patent number: 9966804Abstract: An outer-rotor permanent magnet brushless motor is disclosed, which comprises an outer-rotor and an inner-stator. The outer-rotor configured with P poles, P is a natural number and denotes a multiple of 4. The inner-stator has a stator axle, and S teeth which configured on outer surface of stator, S=P?1, S is a natural number. A circle is formed about a center of the stator axle from the center of the outer end surface. A correction angle a1 and an original angle a are defined from the center of the outer end surface. T The ratio of a1/a is defined by the following formula: 0.2<(a1/a)<0.6.Type: GrantFiled: May 27, 2015Date of Patent: May 8, 2018Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Shou-Long Yu, Yang-Guang Liu, Chia-Hao Hsu, Liang-Chiao Huang, Yu-Choung Chang

Patent number: 9246361Abstract: A segmented magneto-conductive structure applied in rotating machines comprises a rotor assembly and a stator assembly. The rotor assembly includes a rotor yoke component and a plurality of rotor teeth components. The rotor yoke component is made of non-oriented silicon steel. The rotor teeth components are made of grain-oriented silicon steel. The stator assembly includes a plurality of stator yoke components and a plurality of stator teeth components. The stator yoke components and the stator teeth components are made of grain-oriented silicon steel. Thereby, an operational efficiency of a motor applying the segmented magneto-conductive structure is enhanced.Type: GrantFiled: April 2, 2012Date of Patent: January 26, 2016Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Chun-Chung Yang, Shou-Long Yu
