摘要： The invention provides a hybrid electric vehicle employing a permanent magnet type dynamo-electric machine structured such that a torque at a time of reverse rotation is greater than a maximum torque output by a dynamo-electric machine when the dynamo-electric machine normally rotates. Further, the present invention provides a hybrid electric vehicle in which a dynamo-electric machine and an engine are connected to a drive shaft in series and no gear for switching between forward and backward movements is provided, wherein there is employed a permanent magnet type dynamo-electric machine structured such that a torque output by the dynamo-electric machine when the hybrid electric vehicle moves backward (the dynamo-electric machine reverse rotates) is greater than a maximum torque output by the dynamo-electric machine when the hybrid electric vehicle moves forward (the dynamo-electric machine normally rotates). In the hybrid electric vehicle employing the permanent magnet type dynamo-electric machine having a stator having a stator iron core around which a stator coil is wound, and a rotor arranged in the stator at a rotational gap and having a plurality of permanent magnets arranged and fixed within a rotor iron core in a peripheral direction, a ratio between a maximum torque output by the dynamo-electric machine when the dynamo-electric machine normally rotates and a torque output by the dynamo-electric machine when reverse rotating establishes a relation 1:1.05-1.2, whereby the torque at the reverse rotation becomes greater.

摘要： A permanent magnet type electric rotating machine comprises a stator having a salient-pole concentrated winding, and a rotor disposed with a rotational gap, and having a plurality of permanent magnets arranged and fixed in a circumferential direction inside, and an auxiliary salient pole provided between the permanent magnets. A ratio of the number of poles for the rotor and the number of slots for the stator is 2:3 and, when a slot pitch of the stator is τs (electrical angle), an angle θ (electrical angle) made by a circumferential width of the permanent magnet in the surface of the stator side with an axis of the rotor is set at θ≈n×τs/2+8×m (n=1 or 2, and m=1, 2 or 3). Thus, pulsation torque, cogging torque or the waveform distortion of a no-load induced voltage is selectively reduced as occasion demands.

摘要： A rotating electric machine comprises: a stator including a stator iron core having a plurality of slots and a stator winding incorporated in the plurality of slots; and a rotor rotatably disposed in the stator via a clearance; wherein a mold (i.e., a slot insulator) made of an insulating resin is brought into close contact with the surface of a projection (i.e., a tooth core) of the stator iron core, formed between the adjacent slots, the thickness of the mold at a portion of the projection wound with the stator winding being smaller than that of the mold at other portions. Thus, it is possible to provide the rotating electric machine in which thermal resistance generated between the stator winding and the stator iron core can be reduced, thermal transmittance of heat generated in the stator winding to the stator iron core can be enhanced, and the cooling efficiency of the stator winding can be enhanced.

摘要： A non-contact sensor for sensing a rotational position of a rotating object is provided. A ring-shaped permanent magnet magnetized in the axial direction is sandwiched between two pairs of magnetic plates from above and below. Two pairs of upper and lower protruded magnetic substance portions are provided between the upper and lower magnetic plates at opposite outer ends thereof. Magnetic sensitive devices are inserted in air gaps between the two pairs of upper and lower protruded magnetic substance portions. A magnetic flux generated from the ring-shaped permanent magnet is substantially concentrated to the protruded magnetic substance portions and passes the magnetic sensitive devices. The amount of magnetic flux passing each magnetic sensitive device is substantially proportional to the rotational angle of the ring-shaped permanent magnet. The rotational position of the ring-shaped permanent magnet and hence the rotational position of a rotating shaft supporting the ring-shaped permanent magnet can be sensed in a non-contact manner as a signal output from the magnetic sensitive device. Since the magnetic flux is effectively concentrated to positions where magnetic sensitive devices are attached, a non-contact rotational position sensor having high accuracy and high sensitivity can be obtained.

摘要： At least one groove and two grooves extending toward an axial direction of a rotor and is provided on an outer periphery of a rotor iron core or at least one hole is provided in the rotor iron core. By providing the groove and the two grooves on the outer periphery of the rotor iron core or by providing the hole in the rotor iron core, cogging torque is generated to negate the cogging torque which is generated according to the magnetic fluctuation between the magnetic field of the permanent magnets and a stator. As a result, the overall cogging toque in a permanent magnet type rotary machine is reduced.
