    • PURPOSE: To provide a rotary electric machine which can enhance the reliability of a mount. CONSTITUTION: In order to solve the above problem, a permanent magnet type synchronous rotating electric machine 2 has a stator with winding and a rotor 20 which is arranged rotatably via vacant space from the stator and is halved in the direction of a rotary shaft. After that, a position is set where the composite field value of the permanent magnets 21A and 21B is smaller than the specified value, in the case of switching the permanent magnet type synchronous rotary electric machine 2 from a motor to a generator, permanent magnets 21 different in polarity are arranged alternately, and the relative axial position of a second rotor 20B to a first rotor 20A is made a specified position where the composite field values of the permanent magnets 21A and 21B becomes a specified value after being made.
    • 目的:提供可提高安装座的可靠性的旋转电机。 构成:为了解决上述问题,永磁式同步旋转电机2具有带绕组的定子和转子20,转子20经由定子的空隙可旋转地设置,并沿旋转轴的方向减半。 之后,在将永久磁铁式同步旋转电机2从电动机切换到发电机的情况下,设定永磁体21A,21B的复合磁场值小于规定值的位置,永久磁铁21 交替排列极性不同,第二转子20B相对于第一转子20A的相对轴向位置成为永久磁铁21A和21B的复合磁场值在制作后成为规定值的规定位置。
