    • PURPOSE:To improve the reliability by respectively disposing armature windings of AC and DC sides separately at stator and rotor sides, thereby reducing mutual interference. CONSTITUTION:A rotary converter has a rotor 8 and a stator 9 provided at the prescribed interval on the outer periphery of the rotor 8. The rotor 8 is formed of a magnetic rotor body 10 and a conductive cylinder 11 engaged fixedly with the outer periphery of the body, and the stator 9 is formed of a ring-shape wound superconductive field winding 12, a vessel 13, a yoke 14, a current collector of a brush 16, an output terminal 17, and a DC exciting power source 18. Further, a polyphase AC armature winding 19 is disposed in an air gap between the rotor 8 and the yoke 14 of the stator 9, secured to the inner periphery of the yoke 14, and a magnetic shielding plate 20 for protecting the winding 12 against the AC magnetic field by the winding 19 is provided. Thus, when the rotor 8 is rotated, the rotary shaft direction of the cylinder 11 crosses a sole pole magnetic flux phi, a DC voltage is inducted at this portion to produce a DC power from the brush 16.
    • 目的:通过分别在定子和转子侧分别设置交流和直流侧的电枢绕组,从而减少相互干扰,提高可靠性。 构成:旋转变换器具有在转子8的外周以规定间隔设置的转子8和定子9.转子8由磁转子体10和与外周固定的导电性气缸11形成 主体和定子9由环形缠绕超导磁场绕组12,容器13,磁轭14,电刷16的集电器,输出端子17和直流励磁电源18形成。进一步 ,多相交流电枢绕组19设置在转子8和定子9的磁轭14之间的气隙中,固定到磁轭14的内周,以及用于保护绕组12抵抗AC的磁屏蔽板20 通过绕组19提供磁场。 因此,当转子8旋转时,气缸11的旋转轴方向与单极磁通phi交叉,在该部分引入直流电压,从电刷16产生直流电力。
