(54) Electric generating system for vehicle


(57) To allow a detector magnet for a crank angle sensor (51), and a detector magnet for a pulse sensor (52) to be shared.
A permanent magnet (49) for power generation arrayed on an outer rotor (32) is used as a detector magnet. A crank angle sensor (51) arranged opposing to the permanent magnet (49) and a pulse sensor (52) for detecting a leakage flux of the permanent magnet (49), the pulse sensor (52) being shifted from the crank angle sensor (51), are provided on a stator core (33) side. A part of a plurality of permanent magnets (49) is deviated from other part by a deviation amount δ, so that the pulse sensor (52) does not detect a leakage flux of this permanent magnet (49). Moreover, a leakage flux absorption plate (50) is arranged on the side face of the deviated permanent magnet (49). With a set of permanent magnets (49), the signals whose levels change at different timings can be outputted from the sensors (51 and 52), and on the basis of these signals, a three-phase synchronization signal and an ignition reference position signal can be formed.
