PURPOSE: An electric power supply device for supplying power to at least one equipment item of a rotary rotor for aircrafts and an aircraft are provided to have simple maintenance by removing the device from a rotary rotor and to generate a relatively large current in a shaft rotating at a low speed. CONSTITUTION: An electric power supply device(10) comprises a detachable stick(11) which is reversibly fixed on a shaft(5). The stick has an upper tube which is fixed on the shaft and an AC generator(20) which is not rotated with the shaft. The upper AC generator has multiple upper coils(21) fixed on the upper interior of the upper tube. The stick has a rod(13) which supports at least one upper permanent magnet. The permanent magnet is separated from the upper coils by a predetermined upper air gap. At least one upper rolling bearing unit(13') is interposed between the rod and the upper tube. |
