3 Sensors
Two groups of inductance sensors are adopted.The iron cores of both inductance sensors and magnetic poles are alternatively disposed (Fig.4).After the signals of sensors are processed,we can get coordinates of the rotor in the main control plane and displacements of the rotor plumbing the main control plane.
Inductance sensors detect the distance (airspace s) between the rotor and the iron cores through detecting the changes of loop sensors L.The calculation formula
for the sensor loop inductance is:
L means inductance,n means number of windings of the loop,μ0 means the magnetic constant in vacuum,s means the wide of the airspace,Al means gas gap cross section.Taylor expansion of the equation (1) at the balance place s=s0 and adopt the main item:
Let us put a group of sensors as examples in Fig.5.We can get the inductance difference between A and B in equation (3):The result that a group of sensors A and B do the differential is to prorate with the place change (Δs) at the balance place.The proportion modulus is k.The true measurement of the inductance A,B and the place change curve is demonstrated in Fig.6 and Fig.7.The differential curve of the sensor A and B is shown in Fig.8.At the balance place,the inductance difference shows linear relationship with the place of rotor.It inosculates well with the theoretically analytical results.Due to the certain angle formed between sensors and magnetic poles,the signal measured by sensors
should map to the coordinate directions in which magnetic poles are located,the mapping connection of (x,y) → (x′,y′) is:
