  • METHOD FOR ESTIMATING PARAMETERS OF AN ELECTRIC MOTOR AND A POWER FILTER
    Publication number: 20250030366
    Abstract: A method for estimating electrical parameters of an electric motor (205) and a power filter (203) connected to a power converter (201) including injecting an AC signal of different frequencies for a given time window in the power filter (203) and the motor (205), measuring a response signal of the power filter (203) and the motor (205) to the injected AC signal, determining a resonance frequency of the power filter (203) based on the measured response signal, calculating a ratio of leakage inductances of the power filter (203) and the motor (205).

  • Method and device for estimating individual phase resistance of an electric motor
    Patent number: 11637517
    Abstract: The present invention relates to a method for estimating individual phase resistance of a motor by means of an adjustable speed drive (ASD) while the motor controlled by the ASD is running and/or is at standstill. The motor is an asynchronous motor or a synchronous motor. The invention also relates to an adjustable speed drive for executing a corresponding method.
