In the stator of the present invention, a yoke (24) is formed such that the circumferential width thereof is greater at a radial-outer region than at a radial-inner region, i.e., such that the distance (a) between yoke side faces (24A, 24A) gradually increases from a radial-inner region to a radial-outer region, and the distance (b) between two yoke side faces (24A, 24A) opposing each other and facing a space between the tooth-shaped iron cores (11, 11) that are disposed along a predetermined circumference with a predetermined interval is set to be a predetermined value over a range from a radial-inner region to a radial-outer region, or alternatively, is set so as to slightly decrease from a radial-inner region to a radial-outer region. A stator (10) is formed by inserting each of the core back iron cores (12) into a space between the tooth-shaped iron cores (11, 11) adjacent to each other. The present invention also provides a stator in which a packing factor can be increased and the magnetic flux can be made smooth, and a manufacturing method therefor.

    摘要: A control apparatus for an electric motor provided with a rotator having a permanent magnet and with a stator for generating a rotating magnetic field by an applied voltage and revolving the rotator includes: a rectangular wave inverter that applies a rectangular wave voltage onto the stator of the electric motor to drive the electric motor; a voltage converting section that raises or lowers an output voltage of a direct-current power supply and applies the voltage onto the rectangular wave inverter; an electrical angle acquiring section that acquires an electrical angle of the rotator of the electric motor; and an output voltage command generating section that generates a command for instructing the voltage converting section to output an electrical-angle synchronized voltage whose amplitude ripples in synchronization with a change of the electrical angle of the rotator acquired by the electrical angle acquiring section. In response to the command generated by the output voltage command generating section, the voltage converting section raises or lowers the output voltage of the direct-current power supply to a voltage indicated by the command and applies the voltage onto the rectangular wave inverter. This reduces a loss caused by a response delay of the electric motor.

    摘要: A motor controller for an axial-gap motor permits a reduced size of the entire system of including a drive circuit and a power source of the motor, reduced cost, and higher reliability to be achieved by controlling the energization mode of the motor. The motor controller has a torque command determiner which inputs a first DC voltage to a first inverter at least either when a rotor is at a halt or when the number of revolutions of the rotor is a predetermined number of revolutions or less, supplies a field axis current for changing the magnetic flux of a field of the rotor to a first stator from the first inverter such that the amount of energization is temporally changed, converts an induced voltage developed in a second stator by the supplied field axis current into a second DC voltage by a second inverter, and outputs the second DC voltage, thereby charging a second battery.
