In driving said synchronous motor at steady state through phase control, said firing angle (α) is feedback controlled to cancel the phase difference between the mid-point of a zero current plateau of a function of the phase current fed to the electric motor and the zero-crossing point of a counter electromotive force signal (fcem) relative to the same phase. In feedback controlling the firing angle (α), the synchronous electric motor is switched off if the required firing angle (α) exceeds a maximum threshold (α | 04-12-2012 |
