Combined alternator-starter motor for motor vehicle engines, uses magnet attached to inside of drive pulley facing Hall effect sensor housed in face of bearing housing on outside of stator

摘要

The rotor position is detected by a magnet (9) passing a Hall effect detector (10). The magnet is attached to the drive pulley (8) of the alternator-starter unit, and the Hall effect detector is attached to the front bearing (5) on the outside of the stator (2).
