Abstract

Assistance apparatus and computer-implemented method for removing spurious signal components in a measured motor current signal of an electric motor (11) for optimized motor diagnosis, comprising the steps - receiving (S1) the measured motor voltage signal (Um) and a measured motor current signal (Im) measured at the motor (11), - generating (S2) a modelled current signal (Ims) by a motor model (15) depending on the measured motor voltage signal (Um), - generating (S3) a reference current signal (Ips) by the motor model (15) depending on an undisturbed sinusoidal motor voltage signal (Up), - adapting (S4) a noise removal module to infer optimal denoising parameters by inputting the modelled current signal (Ims) and the reference current signal (Ips) into the noise removal module (16), - determining (S5) a denoised motor current signal (Id) by inputting the measured motor current signal (Im) into the adapted noise removal module, and - outputting (S6) the denoised motor current signal (Id) for optimized motor diagnosis.
