Data amplifier for supplying signal of angle sensor arranged at shaft of drive system to signal electronic via electrical lines, has impedance converter arranged between reference signals provided on input and output sides, respectively

摘要

The amplifier has inputs for feeding a reference signal and position signals, and an output provided with another reference signal corresponding to the former reference signal. A difference between the respective position signal and the reference signal is amplified, and the amplified difference is fed to the output. An impedance converter is arranged between the reference signals. The position signals are applied to non-inverting inputs of operational amplifiers (OP2, OP3) via resistors (R1-R11) that are arranged in front of the inputs of the data amplifier. An independent claim is also included for a drive system comprising a shaft with an angle sensor.
