Position sensor system

An inductive position sensor system for high-speed motors, without said sensor system comprising magnets, brushes or magnetic shields,

• the sensor system comprising a sensor which comprises at least one inductor coil and at least one passive coil, the at least one inductor coil inducing voltage in the at least one passive coil, and an electronic signal processing circuit, said electronic circuit comprising a chip for processing a signal corresponding to the magnetic field induced in the at least one passive coil;
• the sensor system also comprising a conductor element which is movable with respect to the at least one passive coil such that the magnetic field induced in the at least one passive coil varies;
• wherein the sensor comprises at least three coils, one of said at least three coils being an inductor coil and two of said at least three coils being passive coils;
• and
• wherein the chip is an analogue chip, said analogue chip supplying an analogue sine-cosine output signal, such that the position can be detected from a reading of the voltage of the passive coil or coils without having to demodulate the signal by means of additional electronics.
