METHOD FOR DETERMINING THE INTENSITY AND ELECTROMAGNETIC TORQUE OF AN ASYNCHRONOUS ELECTRICAL MACHINE DURING OPERATION

摘要

Method for determining a parameter of an asynchronous electrical machine during operation, the machine comprising at least one stator (7) and a rotor rotating relative to the stator about an axis, and radiating, during operation, around the outer surface of the machine, a magnetic field having an axial component, and a magnetic field having a tangential component, the method comprising a calibration phase and subsequently an evaluation phase of the at least one parameter, the calibration phase comprising: a first step for measuring the axial component and, simultaneously, the tangential component, as well as the phase offset between the axial component and the tangential component, for a plurality of values of the intensity ​​absorbed by the machine, then, from the results of the first measurement step, a step of generating a calibration curve in the form of a straight line connecting the absorbed intensity and the axial component.
