Abstract: A method for compensating interference in a measured angle signal of a magnetic angle sensor of an electrical machine, wherein the method includes: receiving a measured angle signal, estimating a current error and/or a misalignment error in the measured angle signal, calculating an expected rotor angle from the measured angle signal, taking into account the estimated current error and/or the estimated misalignment error, such as during operation of the electrical machine. The present invention furthermore relates to a microcontroller for calculating interference in a measured angle signal of a magnetic angle sensor of an electrical machine, to an electrical machine having a magnetic angle sensor and a microcontroller and to a computer program product.

Abstract: A regulating method and device for loss-optimized operation of a separately excited synchronous machine having a stator and a rotor are provided. The method may include: providing reference values for stator and rotor currents, wherein the reference value for the stator current and/or the reference value for the rotor current or an auxiliary parameter representing the reference value of the stator current and/or an auxiliary parameter representing the reference value of the rotor current is dependent on a predefined reference torque; providing maximum values for stator and rotor currents; comparing reference values for the stator and/or rotor currents or an auxiliary parameter representing the reference value of the stator current and/or an auxiliary parameter representing a reference value of the rotor current to the corresponding maximum values and reducing of the reference torque by a torque value if at least one reference value reaches or exceeds the corresponding maximum value.
