Motor vehicle starter-generator has magnet mounted on rotor shaft pulley and Hall effect sensor mounted on front bearing

摘要

The motor vehicle starter-generator has a rotor (1) and stator (2) with a front bearing (5) traversed by the rotor shaft (3). The shaft carries a pulley (8) outside the stator and a magnetic target (9) follows the rotation of the pulley and is mounted on it. A Hall-effect sensor (10) detects the movement of the target and is mounted on the front bearing. The sensors can be mounted parallel to the rotor axis.
