Abstract
A rotation detecting device that includes an electric power generator having a stator and a rotor, said rotor having a plurality of alternating opposite magnetic poles in a circumferential direction of the rotor, at least a first magnetic sensor mounted on either the stator or a support member for supporting the stator and operable to detect the alternating opposite magnetic poles in the rotor; and an electric power supply circuit for utilizing an electric power generated by the electric power generator as an electric power source for the at least first magnetic sensor.
