Abstract (en)

[origin: WO2011098245A2] The invention relates to a method (300) for determining the strength of a magnetization current for an asynchronous motor. Said method (300) comprises a step, in which an individual characteristic curve (200) is provided (310) for the asynchronous motor (120), said curve representing the influence of a magnetization current on at least one winding of the asynchronous motor (120) for a predetermined magnetization current. The method (300) also comprises a step, in which the strength of the magnetization current is determined (320) to magnetize the asynchronous motor (120) using the individual characteristic curve (200) for said motor (120).
