A coil end shaping apparatus shapes three flatwise bent portions fto fin a lead wire portion extending from one end of a coil by bringing first and second shaping dies close to each other such that one of the flatwise bent portions is bent in the direction that is opposite to the direction in which the rest are bent. The second shaping die, which is a movable die, has an clearance portion that prevents a portion of the lead wire portion to be bent along the flatwise direction on the side closest to the free end from being restrained by not contacting the lead wire portion while the flatwise bent portions on the base end side with respect to the flatwise bent portion on the side closest to the free end, of the three flatwise bent portions, are shaped in the lead wire portion.

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. This effectively reduces a variation in torque output to the drive shaft 22 in the course of the switching operation and enables the power to be output to the drive shaft 22 even in the course of the switching operation.

Power output apparatus and method of regulating power

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.

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.

Power output apparatus and method of controlling the same

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.
