Tóm tắt

This paper presents a new approach for the design of incremental angular position and angular speed sensors, using a capacitive technology. Transmitter and receiver segments are integrated with the sensor electronics on a single PCB. As the sensor measures the change of capacitance in dependence of the rotor position, any conductive or dielectric material can be used for the gear-tooth rotor. The carrier frequency excitation and the differential sensor output assure a high level of EMC.
