摘要： PROBLEM TO BE SOLVED: To obtain a high torque characteristic in a low-rotation region and a high output generating characteristics in a high-rotation region by arranging the centers of the same magnetic poles of first field magnets and second field magnets, and shifting the magnetic pole centers of the first field magnets from those of the second field magnets as the direction of torque generated in a rotor becomes opposite. SOLUTION: Armature windings 11 are wound on a rotor core 11, and the rotor core 11 is shrinkage-fitted to a housing 13, which has a cooling water passage. A permanent-magnet embedded rotor 20 is composed of a first rotor 20A fixed to a shaft 22 and a second rotor 20B separated from the shaft 22. The first rotor 20A has permanent magnets 21A arranged so that their polarities become different in order in the direction of rotation. The second rotor 20B has permanent magnets 21B arranged so that their polarities are different in the order in the direction of rotation. The field magnets of the first and second rotors are opposed to the magnetic poles of the stator. A stopper 24 is provided, so that the second rotor 20B does not protrude out from the center of the stator. Consequently, it becomes possible to vary the quantity of effective magnetic flux generated by permanent magnets which are opposed to magnetic stator fields.

摘要： PROBLEM TO BE SOLVED: To omit a wire harness such as a power cable, etc., and improve power loss, in a vehicle driving system of engine/electric motor composite type. SOLUTION: Part 1 of wheels are driven with an engine 3. Wheels 2 other than the wheels driven with the engine 3 are driven with a dynamo-electric machine 4. The dynamo-electric machine 4 is driven as an electric motor for wheel drive to assist an engine drive system when the travel load is as large as that at start or at climbing up a slope. In vehicle drive, there is an operation range where it does not need electric assistant drive such as the time of low/middle load travel or deceleration. At this time when the assistance is needless, the dynamo-electric machine is functioned as a generator so as to convert the mechanical energy from the wheels into electrical energy. The dynamo-electric machine 4, an inverter 7, a capacitor 11, and a controller 18 are unitized integrally, and the unit is attached to a differential gear 5. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a hoist having installable dimensions in a hoist shaft and capable of generating enough torque by forming the hoist as a double speed reducer comprising a planetary gear for the low speed stage and a helical gear for the high speed. SOLUTION: In a hoist shaft, an elevator car 1 and a counter weight 8 balancing the car are suspended by wire ropes 2a-2f. A hoist 7 is installed in the lower part of the hoist shaft. In this case, the hoist 7 is constructed as a double speed reducing gear device, with a helical gear for the high speed stage, and a planetary gear for the low speed stage. Thus, the dimensions in the cross direction and in the direction of height are substantially equal to those of one stage speed reducing helical gear device, and a required speed reducing ratio can be obtained. As a motor, a commercial item of a high speed and low torque type can be used, so that the hoist 7 can be constructed at a low cost, and a brake is provided on the shaft of the motor to reduce the size of the brake device.

摘要： PROBLEM TO BE SOLVED: To provide a thin type hoist whose motor diameter is small and whose brake is compact, by incorporating a reduction gear into a thin motor and forming them integrally. SOLUTION: A field generating means 1A is formed integrally with the inner periphery surface of a rotor 2, and formed integrally with a cylindrical stator 5 at the outer peripheral surface. A motor is constituted of a field generating means 1B which is made to serve as a pair with the field generating means. A permanent magnet may be fixed on either of the rotor 2 or the stator. The rotor is formed integrally or fitted with/onto a rotor shaft 4, and a brake 5 and a center gear 6 are fitted on a coaxial axis to the rotor shaft. An inner tooth 7 is formed at the inner periphery surface of the stator, and an epicyclic gear device is constituted of a planet gear 8 which engages with both of the inner tooth 7 and the center gear 6, and a carrier 9 which rotatably supports the planet gear 8. It is thus possible to facilitate the control of a thin hoist and decrease the diameter of the motor for formation of a compact brake 5.

SOLUTION: In at least either one of a driving gear and a driven gear, the tooth depth is changed along the tooth trace so that the overall contact ratio becomes substantially an integer. or, the tooth depth is gradually decreased along the tooth trace toward the end of the tooth thereby allowing the tooth tip ridge line of the section where the tooth depth gradually decreases to approximately parallel with the simultaneous contact line, or, the tooth depth is changed along the tooth trace so that the change of the total of the lengths of the simultaneous contact lines accompanying the progress of engagement is minimized, or, the tooth depth is changed along the tooth trace, and the contact ratio is set to be approximately 2 or 3 in a first area where the tooth depth is short, whereas in a second area where the tooth depth is larger the contact ratio is set to be larger than that of the first area and the spring constant of the tooth is approximately equalized to the spring constant of the tooth in the first area.
