摘要： The present invention is intended to provide a magnetic gear structure that realizes a magnetic gear that transmits a torque efficiently by reducing eddy currents generated in the interior of magnets. In order to solve the subject described above, in the magnetic gear structure, a structure in which magnets are arranged in the interior of an iron core in an inner rotor portion. Bonded magnets formed by molding, for example, NdFeB powder may be used as the magnets. Since the influence of the eddy current on the side of an outer rotor having a larger pole number is large, a structure in which the magnets are arranged in the interior only of an outer rotor portion having a larger pole number is also applicable. In addition, the magnets to be embedded may be divided into a plurality of pieces. The finer the division of the magnets, the less eddy currents are generated, so that a method of further fining down and assembling the same is also effective. Further reduction of the eddy currents is possible by laminating the plate-shaped magnets having a thickness equivalent to an electromagnetic steel plate in the axial direction.

摘要： A control technology for a synchronous motor for suppressing rotational pulsation caused by variation in individuals without making a control algorithm complex is provided. In a motor drive system which is a control device for a synchronous motor, in order to suppress the pulsation component of N times as high as the AC frequency for driving the synchronous motor, a controller in which the phase property of the disturbance response of the controller with respect to the pulsation frequency is within ±45° is arranged. Therefore, the torque pulsation component generated from distortion in induction voltage or variation between phases is suppressed.

摘要： Control technique of a synchronous motor capable of suppressing rotation pulsation caused by individual difference without complicating control algorithm is provided. A pulsation generator superimposing a pulsation component anticipated in advance to a current command for the synchronous motor and a correction current generator superimposing a correction signal substantially having an average value of zero to the current command are provided in a synchronous motor control device. By this configuration, the correction signal suppressing a distortion component is superimposed to a value of the current command with a simplified control configuration. Torque pulsation is suppressed by determining the correction signal from difference between a detection current and a command current.

摘要： The present invention enables modulated wave signals having extremely small waveform distortion to be generated using a relatively simple circuit, and thereby it is possible to hold down vibrations and noise of a motor, which are attributable to torque ripples. In order to remove defects of the conventional techniques, the circuit generates a plurality of trapezoidal wave signals having at least two constant levels based on position sensing signals of magnetic pole of a motor, generates quasi-sinusoidal wave signals at a quasi-sinusoidal wave modulator based on the plurality of trapezoidal wave signals, and compares the quasi-sinusoidal wave signals with a carrier wave so as to perform PWM control of an inverter.
