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： It is necessary to keep the positional relation between a stator and a housing for a long time, so the stator and housing must be fixed to each other with increased adhesive strength. Since this kind of rotary electric machine is a mass-produced product, the fixing method is demanded to be simple enough to be suitable for mass production. In order to meet this demand, in a rotary electric machine, for bonding and fixing the stator and the housing for covering the stator by synthetic resin, a plurality of projecting parts are formed on the inner circumference of the housing and synthetic resin is poured into between the stator and housing to bond and fix the stator and housing.

摘要： Provided is an AC motor in a three-phase unbalanced state such as a claw-teeth type AC motor (108), which is reduced in magnetic flux pulsations and torque pulsations. Among the current command values of individual phases to be intrinsically given to an inverter (106) for feeding three-phase alternating currents of variable voltages/frequencies to the electric motor, a current command of an intermediate phase (a V-phase) having a smaller magnetic resistance of a stator core than those of other phases is subjected to a reducing correction by a correction unit (102) on the basis of the correction amount calculated by a current correction amount calculating unit (103), and the unbalanced three-phase alternating currents are fed to the AC motor (108), so that magnetic flux pulsations of a secondary electric angle and torque pulsations of the same order are reduced.
