Rotary electric machine with improved energy efficiency |
摘要 |
A rotary electric machine configured with a stator, rotor, and permanent magnets disposed in an inverted V-shape that becomes gradually narrower from a side of a center of rotation of the rotor. The rotor is provided with a plurality of support portions that extend radially about the center of rotation, and gap portions are respectively formed in correspondence with the plurality of support portions at positions spaced by a predetermined distance from an edge portion of the permanent magnets in a flowing direction of magnetic flux between the permanent magnets and the stator. The gap portions are formed to have such a length that causes magnetic saturation during generation of low torque in a low-current state and that causes no magnetic saturation during generation of maximum torque in a high-current state in which electricity at a high current is supplied to the stator coil. |
