Induction sensor for determining rpm in antilock system

摘要

The rotor (12) is designed as a pulse wheel taking a subordinate role, at least one toothed section (11) at its circumference. The flux concentrator (2) and the pulse wheel are provided respectively with an equal number of teeth (17) over their entire respective circumference.The flux concentrator is horse shoe shaped is arranged around the stator winding (8). The magnetic ring (4) is magnetised axially unipolar or radially multipolar. The toothed section of the pulse wheel is arranged radially outside or radially inside the toothed section (6) of the flux concentrator.
