Electronic circuit for determining angle position of e.g. rotor, of motor vehicle electrical machine, has power supply device, output stage and output device commonly arranged on substrate, where sensor device is formed as resolver

摘要

The electronic circuit (1) has a output stage (4), which activates a sensor device (7), and an output device (5) outputting information about an angle position of a rotating part. A power supply device (3), the output stage and the output device are commonly arranged on a substrate (2). The sensor device is formed as a resolver. The resolver outputs a cosine signal and a sine signal depending on the angle position, where amplitudes of the signals are dependent on the angle position, where the output device is formed as an analog to digital converter.
