    Abstract: PROBLEM TO BE SOLVED: To reduce maximum load capacity of an assist motor, and also reduce maximum current value of an inverter circuit for driving the assist motor. SOLUTION: A control unit 90 sets a WOT line L2 as a boundary of an overdrive area and an underdrive area, when a coupling condition of an assist motor 40 is an overdrive linking condition (S104). The control unit 90 determines a desired coupling point of a drive shaft, namely an outer rotor shaft 35 from a required output (S106). When the desired operating point is in the underdrive area, the unit selects the WOT line L2 for maximizing a torque of an engine 50 as an operating line of the engine 50 (S116), and marks a switch flag from the overdrive coupling to the underdrive coupling (S118). Thereby, the overdrive coupling is switched to the underdrive coupling, and when the operating point of the drive shaft, namely the outer rotor shaft 35 is in the underdrive area, the WOT line L2 is used as the operating line of the engine 50.

    Abstract: PROBLEM TO BE SOLVED: To detect an electrical angle with accuracy and ideally control the angle by impressing a pulse voltage having an arbitrary time interval upon multiphase coils and detecting the variation of the currents flowing to the coils. SOLUTION: A pulse voltage having an arbitrary time interval is impressed upon the multiphase coils U, V, and W of a motor-driven rotary machine 60 and the variation of the currents flowing to the coils U, V, and W caused by the impressed voltage is detected. Thus the detected electrical angle between the rotator and stator of the machine 60 is measured. Namely, the driving condition of the machine 60 is detected in advance and the relative timing after the impression of the pulse voltage is started is decided to a prescribed timing in the pulse voltage impressing duration as the detecting timing of the variation of the currents flowing to the coils U, V, and W in accordance with the driving condition of the machine 60. At the decided detecting timing, current detectors 12 and 14 detect the variation of the currents flowing to the coils U, V, and W and an electrical angle detecting section 40 decides the electrical angle based on the detected variation. In addition, a control section 20 controls the machine 60 based on the electrical angle.

    Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of eddy currents on the punched end faces of a stator core formed by laminating blank stator materials upon another, without coating the end faces with insulating films. SOLUTION: A stator core for rotary electric machine is formed, by alternately laminating two kinds of blank stator materials 22 and 32 having different external forms upon another. Since the materials 22 and 32 have different external forms, all punched end faces of the formed stator core 20, such as the outer peripheral surfaces, inner peripheral surfaces, and end faces of tooth sections do not become smooth. Consequently, the occurrence of nonconformities such as efficiency deterioration due to heat generated from the core 20, etc., resulting form eddy currents which may occur, when the punched end faces are smooth can be prevent.
