Measurement of the Rotor Position of an Active Magnetic Bearing Using Interpolar Stray Flux
The very most active magnetic bearings need somehow natured shaft measurement systems. To reduce the significant cost which are caused by the measurement systems a HALL-principle based system is proposed where low budget industrial standard sensors are applied. Contrary to other approaches the HALL-sensors are integrated between the bearing poles instead the air gap. Thus the use of low budget sensors is enabled.
