    摘要: A stator for a two rotor single stator type electric motor is described. The electric motor has inner and outer rotors that are rotated independently within and around a stator upon application of current to the stator. The stator comprises a stator core including a plurality of stator teeth that are circumferentially arranged around a common axis. Each stator tooth includes a plurality of flat magnetic steel plates that are aligned along the common axis while intimately and closely contacting to one another. The stator further comprises at least one connecting ring plate that is coaxially installed in the stator core in such a manner that the ring plate is intimately put between adjacent two of the flat magnetic steel plates of each stator tooth. The ring plate is of an endless annular member.

    摘要: A control device for a plurality of rotating electrical machines has a single current control device with an inverter, gate driver, and a motor controller, which supplies a control current to each rotating electrical machine allowing rotation control in response to the rotational phase of the rotor. In this control device, the current control device determines the control current of each rotating electrical machine based on the target torques and rotational angular velocities of all rotating electrical machines, and supplies a composite current obtained by combining the determined control currents for each rotating electrical machine to all rotating electrical machine. In this control device for a plurality of rotating electrical machines, the required voltage does not exceed the voltage of the power source and the peak value of the composite current does not exceed the permitted range of the inverter.
