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. |
