Abstract
A method for monitoring a rotational angle sensor on an electrical machine. It is desired to provide a method that enables fault detection at both high speeds and low speeds of the rotor. The electrical power of the machine is measured and a power value is estimated using the output signal of the rotational angle sensor, a residual being formed from the measured power and the estimated power and the time curve of the residual being monitored.
