Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient embedded magnet motor for electric vehicles. SOLUTION: With respect to motors for electric vehicles, the production of a minor loop in the excitation of its armature core is prevented or reduced, and thereby the efficiency of the motor is enhanced by increasing the inclination of the distribution of magnet magnetic flux in the gap between field magnets and an armature between the magnetic poles of the field magnets. In addition, the width of the tips of the armature teeth opposed to the field magnets is so controlled that the width is not loss than the intervals between the adjacent field magnets to obtain a highly efficient embedded magnet motor for electric vehicles. With respect to a control method for the embedded magnet motor for electric vehicles, the angle of lead and magnitude of armature current are controlled, so that the direction of the inclination of magnetic flux distribution in the gap between the filed magnets and the armature between the magnetic poles of the filed magnets is constant, and thereby the production of minor loops is prevented or reduced.

Abstract: PROBLEM TO BE SOLVED: To improve the space factor of the coil for an electric machine and to shorten wiring between the coil and a controller. SOLUTION: End members 20 are arranged on both ends of a stator core 10. Almost straight slot in-slot conductors 16 are arranged in slots 14 of the stator core 10. Coil end conductors 28 which bridge the in-slot conductors 16 are arranged in the end members 20. Control elements 30 are installed integrally in the end members 20. Since the in-slot conductors 16 are almost straight, they can easily be inserted into the slots 14, and the space factor is also improved. A coil is formed by connecting the end members 20 to the stator core 10, and a controller is integrated with an electric machine. Thus, the wiring of the coil and the control elements 30 becomes short and electromagnetic noise and a copper loss, which are generated from it, can be reduced.

Abstract: PURPOSE:To realize a torque constant variable type motor having a smaller size and a simpler structure. CONSTITUTION:A cylinder 45 is assembled in a rotor body 16. A piston 46 for driving a motor hydraulically or by a ball screw in an axial direction is provided in the cylinder 45. The piston 46 is coupled to a thrust ring 28 through a bearing 48, and the ring 28 is coupled to a yoke 22. When the piston 46 moves in an axial direction of a rotor, this movement is transmitted to the yoke 22 through the ring 28, and the yoke 22 and a permanent magnet 24 on its surface slide in the axial direction of the rotor. A positional relationship to a core 34 of a stator is varied, and an operating magnetic flux area and/or gap is altered. As a result, an output torque and a maximum speed are varied. Accordingly, since means for varying the positional relationship between the rotor and the stator is assembled in the rotor, an entire structure is simplified and reduced in size.

Abstract: PROBLEM TO BE SOLVED: To make it possible to charge a storage device even while a car is stopping and supply motive power to driving wheels even when the car is stopping or it is running at low speeds by providing the car with a means that switches a mode from the one at which motive power generated by an internal combustion engine is differentially distributed to the driving wheels and a first rotary electric machine to the one at which the motive power is distributed onto to the first rotary electric machine. SOLUTION: In a car, a motive power distribution mechanism 38 is installed that distributes the output torque of an internal combustion engine 28 to a generator 24 and a motor 10. Between the motive power distribution mechanism 38 and the motor 10, a blocking mechanism 40 and a clutch 36 are installed in this order. By connecting or disconnecting the motive power distribution mechanism 38 and the motor 10 by means of the clutch 36, an efficiency to transmit motive power from the internal combustion engine 28 to driving wheels 14 can be kept high independent of a speed of the car and a battery 18 can be charged while the car is stopping.

Abstract: PURPOSE: To reduce variation of an output torque (ripple) to lessen uneven rotation as a motor by providing at least a part of the salient poles to the area deviationally arranged at the rear side of the rotating direction of a rotor providing a plurality of permanent magnets. CONSTITUTION: In a synchronous 3-phase motor 40, four permanent magnets 51 to 54 are respectively provided at the positions shifted by 90 degrees in terms of the mechanical angle and the projected poles 71 to 74 provided between these permanent magnets are also provided keeping the interval of 90 degrees in terms of the mechanical angle. The salient poles are shifted toward rear side for rotating direction of the rotor 500 and is provided at the position in contact with the end portion of the permanent magnet located at the rear side of the salient pole. When the salient pole is located to the rear side of the rotating direction of the rotor 500, an average value of the output torque becomes a little higher than that in the case where the salient pole is not shifted to the rear side of the rotating direction without relation to the opening angle of the salient pole and the torque ripple is reduced in the range of 20 to 32 degrees of the opening angle.
