SINGLE POLE ROTARY ELECTRIC MACHINE

PURPOSE:To enable to increase the capacity of a rotary electric machine by generating a high voltage by a high peripheral speed in a rotary generator section, and collecting a current via a current collecting brush which slidably contacts in a rotary current collector by a low peripheral speed in the collector. CONSTITUTION:A stator is composed of an exciting winding 1, a core yoke 2, a current collecting brush 4, a cylindrical return conductor 3 and an output terminal 5, etc. A rotor is constructed of a hollow cylindrical conductor 7, a riser 8, and a commutator 10. The conductor 7 as a generator section is rotated at a high speed to induce a high voltage. The current is collected by the commutator 10 which rotates slower than the conductor 7 and the brush 4 which slidably contacts with the commutator 10.
