Angle Measurement 0…360°
A pole ring / magnet wheel is mounted on a rotating axis.
Example: Angle measurement, Indicator [ ° ], resolution
0.1°, pole ring (D=48mm) with 60 Poles per
2.5 mm
P02=3 / P03=1 / P08=
P08 = (360° / resolution) / (Number of
poles* 250)
(e.g.: (360° / 0,1°) / (60 * 250) = 3600 / 15000 = 0,24
P02=3 / P03=1 / P08=0,2400
Technical Data
A pole ring / magnet wheel is mounted on a rotating axis
(e.g. motor shaft).
Example: Spindle drive with gear box, the pole ring at the
engine, indicator [mm], resolution 0.01mm, pole ring
(D=48mm) with 60 poles per
2.5 mm, transmission
reduction = 10:1, Distance per spindle revolution = 3mm
P02=0 / P03=2 / P08=
