Inductive position/speed sensing

Inductive position/speed sensing

Replacing the coils of conventional resolvers, encoders, and LVDTs with a silicon chip allows position measurement miniaturization at maintained or better performance. A micro-coil matrix, integrated interface circuit, package, and external scale in anymetallic material make up the sensor.

To work, one of the micro-coils generates a field, modulated by the metallic scale. This amplitude-modulated field imparts an induced voltage in the detector micro-coils. Interface circuitry processes the AM signal to deduce position, speed, and direction of movement. Output can be analog, digital, or any other format required by the application.
