6.3.3 Stamped Steel Exciter Ring
A well-designed and manufactured exciter ring produces a clean wheel speed
signal. In this respect, a stamped steel exciter ring produces very good results
since the teeth are defined by through-holes, and tooth definition (i.e. edge
sharpness) is excellent. However, these types of rings are easily damaged
before installation on the vehicle, so extra care is required to ensure that they are
properly mounted and are running true.
6.3.4 Machined Steel
In the case of a steel exciter ring, the height of each tooth becomes important.
Manufacturing considerations influence the solution and a tooth height of 0.078
inches (1.98mm) is common. To obtain a well-defined wheel speed signal, it is
important that the sensor pole piece does not bridge the gap between one tooth
and the next (nominally 0.078 inches/1.98mm). Magnetic flux saturation will
occur and the signal will be degraded.
6.3.5 Oil Seals
Oil seals must clear the inside diameter of the exciter ring and must not extend
beyond the face of the ring. Consult the hub supplier for further information.
