Abstract
An encoder alternator for an internal combustion engine has a rotor with a plurality of circumferential magnetic rotor poles in a periodic pattern except for at least one magnetic irregularity. A sensor coil is wound around a stator pole and outputs a crankshaft position sensor signal when the magnet irregularity of the rotor passes the stator pole.
Claims7
An alternator for an internal combustion engine having a rotary crankshaft, said alternator being driven by said crankshaft and supplying electrical power for said engine, comprising a permanent magnet rotor mounted for rotation by said crankshaft and having a plurality of circumferential magnetic rotor poles with spaced north-south pole borders in a periodic pattern except for at least one magnetic irregularity, a stator mounted to said engine and having a plurality of stator poles for magnetic flux coupling with said permanent magnet rotor poles, an output current coil wound around designated stator poles and generating charging current providing said electrical power, at least one of said stator poles having a sensor coil would therearound and outputting a crankshaft position sensor signal when said magnetic irregularity of said rotor passes said one stator pole.
