摘要： PROBLEM TO BE SOLVED: To vary the gap between a rotor and a stator without increasing the size of an axial motor.
SOLUTION: A screw 20 having a central axis substantially coinciding with the rotary axis of a rotor is provided at the outer circumferential part of a shaft 14 secured to a housing, and a stator 12 is supported on the shaft 14 by means of the screw 20. When the gap between the rotor 10 and the stator 12 is varied, the stator 12 secured by a brake 16 is released and a current being fed to the coil of the stator 12 is controlled to generate torque in the rotor 10. The stator 12 rotates along the screw 20 and moves in the direction of the rotary axis of the rotor, and the gap between the rotor 10 and the stator 12 is varied.

摘要： PROBLEM TO BE SOLVED: To attain an effective operation in an inverter system provided with two inverters. SOLUTION: A three-phase motor currents are fed to a correction voltage addition/subtraction judging section 102. The addition/subtraction judging section 102 judges whether two of the three-phase motor currents are positive or not. If two are positive, a positive correction voltage ΔV is fed to an adder 104 and if two are negative, a negative correction voltage ΔV is fed to the adder 104. Output from the adder 104 is the voltage command value of a motor and the neutral voltage of the three-phase motor is corrected by adding the correction voltage. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To enhance the upper limit of the output torque from a motor without affecting the voltage of a capacitor as a drive power source. SOLUTION: A DC power source 40 is connected between the neutral points of the three-phase coils 24 and 26 of two Y connections without discrepancy of winding angle which are supplied severally with three-phase AC power from two inverter circuits 30 and 32 sharing a positive electrode bus 34 and a negative electrode bus 36, and also a capacitor 38 is connected between the positive electrode bus 34 and the negative electrode bus 36. The supply of the three-phase AC power is performed by the PWM control by the comparison between modulated waves, where tertiary harmonics having the same amplitude and frequency mutually in the same phase are superposed each on the three-phase modulated waves having the same amplitude and frequency mutually in the same phase, and triangular waves. Consequently, it is possible to enhance the upper limit of the output torque from a motor by reducing the amplitude maximum value of the modulated waves without oscillating the potential difference between the neutral points, that is, the voltage of the capacitor.

摘要： PROBLEM TO BE SOLVED: To improve the motor characteristics of a multi-phase motor and a 2Y motor. SOLUTION: The stator structure of the motor comprises a rotor, which generates a magnetic field flux and a stator where a plurality of pairs of stator coils in a plurality of phases that generate a rotating magnetic field for rotating the rotor are wound on a stator core. By eliminating the overlapping of rotor coils, the interference between coils is suppressed, resulting in a symmetrical torque which is applied to the rotating shaft of the motor, to prevent the wobbling of the rotary shaft of the motor. By suppressing unbalance between UVW phases instead of permitting the overlapping of the rotor coils, self-inductance can be uniformized. As a result, current controllability is improved. These can be applied to both the multi-phase motor and the 2Y motor. In another mode, by devising an arrangement of an armature winding for interlinking the teeth, the magnetic flux generated at the armature winding is cancelled each other. So, the current of zero-phase that flows the armature winding which interlinks the teeth, which is a problem specific to the 2Y motor, can be removed. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：提高多相电机和2Y电机的电机特性。解决方案：电动机的定子结构包括产生磁场磁通的转子和定子，其中产生用于旋转转子的旋转磁场的多对定子线圈被缠绕在定子铁芯。通过消除转子线圈的重叠，可以抑制线圈之间的干扰，从而产生施加到电动机的旋转轴上的对称扭矩，以防止马达的旋转轴摆动。通过抑制UVW相之间的不平衡，而不是允许转子线圈的重叠，自感可以被均匀化。结果，电流控制性提高。这些可以应用于多相电机和2Y电机。在另一种模式中，通过设计用于使齿互连的电枢绕组的布置，在电枢绕组处产生的磁通相互抵消。因此，可以除去流经电枢绕组的零相电流，这是相互连接的，这是2Y电机特有的问题。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce a current capacity that flows into and out of a capacitor. SOLUTION: A voltage boosted by a boosting converter CONV1 is accumulated in a smoothing capacitor C. This voltage is supplied by inverters INV1, INV2 to motors MG1, MG2 as prescribed AC currents. By adjusting the phase or frequency of a carrier wave in the PWM control of a switch in the boosting converter CONV1 and a carrier wave in PWM controls of switches in the inverters INV1, INV2, pulse currents from the inverters INV1, INV2 that flow into and out of the smoothing capacitor C are offset with a pulse current from the boosting converter CONV1 so that the capacity of the current that flows into and out of the capacitor C is reduced.
