Patent ID: 7224093

Claim:
Multi-phase rotating electric machine adapted to be used in a motor vehicle, having an internal-combustion engine, as an electrical generator and as an electric motor for starting of the internal-combustion engine, comprising: a hollow support (S) equipped with a front end plate ( 13 ) and with a rear end plate ( 14 ), a multi-phase stator ( 8 ) carried internally by the hollow support (S), a rotor ( 4 ) surrounded by the multi-phase stator ( 8 ), a shaft ( 3 ) carrying the rotor ( 4 ), means ( 50 , 52 ) of the magnetic type for tracking the rotation of the rotor, said means ( 50 , 52 ) of the magnetic type comprises a target holder ( 60 ) locked in rotation onto the rotor ( 4 ) and mounted adjacent thereto, wherein said rotor ( 4 ) comprises magnetic poles, each of said front ( 13 ) and rear ( 14 ) end plates comprises bearing means ( 11 , 12 ) traversed by the end of the shaft ( 3 ), a target ( 50 ) fixed onto the target holder ( 60 ) and at least one sensor ( 52 ) associated with the target ( 50 ) for detecting the passing of the magnetic target ( 50 ), said target ( 50 ) is installed axially between the rotor ( 4 ) and one of the front ( 13 ) and rear ( 14 ) end plates, said one of the front ( 13 ) and rear ( 14 ) end plates is adjacent to the target holder ( 60 ) and carries the sensor ( 52 ), wherein said at least sensor ( 52 ) is mounted on a sensor holder ( 53 ) fixed to said one of the front ( 13 ) and rear ( 14 ) end plates on the side opposite to the rotor ( 4 ), wherein the sensor holder ( 53 ) features oblong apertures receiving and fixing said at least one sensor ( 52 ) with angular adjustment to said one of the front ( 13 ) and rear ( 14 ) end plates on the side opposite to the rotor ( 4 ).
