P5.5 - High Precision and Simple Analog Through-Shaft Magnetic Sensors for the Control of Electric Drives

M. Delbaere, G. Masson, Th. Dorge, D. Frachon & St. Biwersi
Many synchronous electric motors require a very accurate position sensor compatible with a sinusoidal control that will enable a very efficient and smooth operation enhancing the comfort by limiting vibrations. This feature is for example important for large power drives for electric or hybrid electric vehicles where the electric machine is located in between the combustion engine and the transmission requiring a very large through shaft design. More generally, these sensors need to keep a...
