| description | The present invention refers to the use of phase advance in motors with non-ideal induced voltages, especially in motors with induced voltages that present a flat region, to avoid instability in the control, wherein the first step is to detect the passage of the voltage induced by the flat region of instability, and then apply a fixed increment in the phase advance in order to avoid the flat region. Detection can be done in two ways: by direct measurement of induced voltage; and measuring the extinguishing time of the freewheel current. |
