Abstract
The invention relates to an electric device () comprising an alternating current electric motor () and a control inverter () for controlling the phase or phases of the motor (). The motor () comprises, on at least one winding of at least one phase (PA, PB, PC), a point (Ma, Mb, Mc) for measuring a voltage relative to a predefined potential (M), the measurement point (Ma, Mb, Mc) being chosen so that it divides the winding into a first (Za; Zb; Zc) and a second (ZaZbZc) portion such that the electromotive forces (e, e) induced in the two portions are phase-shifted relative to one another and means (A;B;C) for measuring the voltage between the measurement point and the predefined potential. The invention also relates to an associated method for measuring electromotive forces.
