Patent ID: 7339294

Claim:
A vehicular starting and charging rotary electric machine sewing as an electric machine or generating machine, comprising: a rotor having a field winding; a stator having a stator winding; a bracket for supporting the rotor and the stator; a brush one end of which is brought into contact with the rotor for supplying field current to the field winding of the rotor; a brush holder for holding said brush; and a magnetic pole position detecting sensor arranged coaxially with a rotating shaft of the rotor, for detecting a magnetic pole position of the rotor, wherein the magnetic pole position detecting sensor is integrally fixed on the bracket, wherein said brush and said brush holder are arranged inside said bracket, and said magnetic pole position detecting sensor is arranged outside said bracket, and wherein said brush is in sliding contact with at least one slip ring, the slip ring being disposed at a same side of the rotor as the magnetic pole position detecting sensor.
