5.2 Measurement with pole ring
5.2.1 Indirect Distance Measurement
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
Æ P02=0 / P03=2 / P08=
Displayed Value/R
magnet wheel
= Number of
poles* 250
(e.g.: 60 * 250 = 150.00 mm)
Measuring Distance/R
magnet wheel
= 3 mm / 10 = 0.3 mm
Æ P08 = Measuring Distance /R
magnet wheel
/ Displayed Value
/R
magnet wheel
= 0.002
Æ P02=0 / P03=2 / P08=0,002
5.2.2 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
Æ P02=3 / P03=1 / P08=
P08 = (360° / resolution) / (Number of
poles* 250)
(e.g.: (360° / 0,1°) / (60 * 250) = 3600 / 15000 = 0,24
Æ P02=3 / P03=1 / P08=0,2400
