Abstract: A terminal module includes a ring-shaped rail having a groove extending in a circumferential direction, a bus bar fitted into the groove, and a connector portion having a connector terminal connecting the bus bar with an external wire. The rail has a phase determining hole for determining a phase of rotation of the rail about an axial direction.

Abstract: A cassette coil comprising an insulator bobbin including a core tube around which a wire coated with an insulating film is wound, forming a coil, and a pair of plate-shaped flanges provided at both ends of the core tube, the flange including a cutout portion opening in a side, wherein the cassette coil includes an insulation wall between a winding start part which is one end of the coil of the wire and an outermost wire part located on the outermost side of the coil of the wire and close to the flange.

Abstract: A power output apparatus 20 implements a smooth switching between the connection of a rotor-rotating shaft 38 of an assist motor 40 with a crankshaft 56 of an engine 50 and the connection of the rotor-rotating shaft 38 of the assist motor 40 with a drive shaft 22, and enables the power output from the engine 50 to be output to the drive shaft 22 with a high efficiency. The power output from the engine 50 is converted to a desired power by a clutch motor 30 having rotors 31 and 33 respectively linked with the crankshaft 56 and the drive shaft 22 and by the assist motor 40 connected to either the crankshaft 56 or the drive shaft 22 via a first clutch 45 and a second clutch 46, and is output to the drive shaft 22. The connection of the assist motor 40 is switched in the state where both the clutches 45 and 46 are set in ON position, when the revolving speed of the engine 50 is made coincident with the revolving speed of the drive shaft 22.

Abstract: A controller for driving permanent magnet type synchronous motor. A motor terminal voltage or IPM (intelligent power module) input voltage necessary to achieve a target operating point is computed based on torque command and motor revolution. When the computed voltage exceeds an actual battery voltage, a booster is inserted between the battery and IPM, and the battery voltage, after being boosted, is applied between the direct current terminals of the IPM. Since the motor terminal voltage can be made so as to not exceed the boosted voltage even if the motor terminal voltage rises along with a rise in revolution and speed voltage, field weakening control becomes unnecessary.

Abstract: A power output apparatus 20 includes an engine 50, a clutch motor 30 having rotors 31 and 33 respectively linked with a crankshaft 56 and a drive shaft 22, an assist motor 40 attached to a rotor-rotating shaft 38, a first clutch 45 for connecting and disconnecting the rotor-rotating shaft 38 to and from the crankshaft 56, a second clutch 46 for connecting and disconnecting the rotor-rotating shaft 38 to and from the drive shaft 22, and a controller 80 for controlling the motors 30 and 40. The controller 80 operates the clutches 45 and 46 according to the states of the engine 50 and the drive shaft 22 and changes the connection of the rotor-rotating shaft 38, so as to enable power output from the engine 50 to be efficiently converted by the motors 30 and 40 and output to the drive shaft 22.

Abstract: A device and method for detecting a failure which are used with an AC motor control circuit to detect a failure in a total of three current sensors correlated to phases U, V, W of a motor. Three types of current paths are formed in order to position two current sensors on each current path while providing an adequate time interval so as not to rotate the motor. By comparing output from each current sensor with a reference value, or by comparing respective output from the two current sensors provided on the same current path, a failure in the respective current sensors is detected. The motor need not be driven in order to detect a fail in the current sensors.
