Patent number: 9231445Abstract: A rotor (10) for a rotary electric machine has a plurality of magnetic poles (24) provided at intervals, in a circumferential direction, at the outer periphery of a rotor core (12). Each of the magnetic poles (24) has a first permanent magnet (26) buried in the center of the magnetic pole, and a pair of second permanent magnets (28) that are buried on both sides of the first permanent magnet (26) in the circumferential direction, and that are disposed such that a mutual spacing between the pair of the second permanent magnets (28) becomes narrower inward in the radial direction. A narrowest spacing between the pair of second permanent magnets (28) is set to be wider than a longitudinal-direction width of the first permanent magnet (26) in a magnetic path region (30) that is defined by the first permanent magnet (26) and the pair of second permanent magnets (28).Type: GrantFiled: February 2, 2012Date of Patent: January 5, 2016Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD., DENSO CORPORATIONInventors: Shinya Sano, Ken Takeda, Tomohiro Inagaki, Shinichi Otake, Tsuyoshi Miyaji, Yuta Watanabe, Ryosuke Utaka

Patent number: 8174244Abstract: A test circuit first detects whether or not a relay unit is normal, and then examines an operation of leakage detecting circuit. This allows relay unit to interrupt an electric power supply path including power lines more securely if electrical leakage occurs in the electric power supply path. If welding in the contact of the relay unit is detected before starting charging of a power storage device included in an electrical device, a control device does not allow the charging of the power storage device, which can prevent a problem from occurring in the electrical device.Type: GrantFiled: June 10, 2008Date of Patent: May 8, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventor: Shinichi Otake
