Patent number: 10014746Abstract: In a rotary electric machine, wound wires are connected to a first terminal and a second terminal. Circuit terminals that are configured from a conductive metal other than aluminum, and the first terminal and the second terminal that are configured from a metal with a principal component of aluminum are joined together inside a circuit chamber that has high water resistant properties. Corrosion is accordingly suppressed at join sites of the circuit terminals with the first terminal and the second terminal. There is therefore no need to coat the join sites with for example a sealing material in order to suppress corrosion at the join sites. Good electrical continuity is accordingly enabled between the circuit terminals and the wound wires while suppressing an increase in costs, even when the wound wire is configured from a metal with a principal component of aluminum.Type: GrantFiled: August 2, 2017Date of Patent: July 3, 2018Assignee: ASMO CO., LTD.Inventors: Hidenori Kanda, Shigeaki Kageme, Takahiro Nakayama, Yoshiyuki Takabe

Patent number: 8232703Abstract: In an embedded magnet motor, radial magnets and first inclined magnets form north poles. The radial magnets and second inclined magnets form south poles. Core sheets each include preformed radial accommodating slots the number of which is expressed by P/2. Some of the preformed radial accommodating slots are short slots and the rest are long slots. The short slots are located at some parts of each radial accommodating slot along the axial direction. Radially inner ends of the short slots restrict the radial magnets from moving radially inward.Type: GrantFiled: November 15, 2011Date of Patent: July 31, 2012Assignee: ASMO Co., Ltd.Inventors: Takahiro Nakayama, Hirotaka Itoh, Yoshiyuki Takabe
