METHOD AND DEVICE FOR CONTROLLING AN EXCITATION SYNCHRONOUS SYNCHRONOUS ROTARY ELECTRIC MACHINE AND ALTERNATOR MOTOR VEHICLE CORRESPONDING THEREOF

摘要

The method according to the invention is of the type of those comprising a control step for motor operation of the machine (12) in which phase currents are driven in full-wave mode in phase windings (u, v, w ) a stator (10) of the machine which is connected to an on-board electrical network (2, 15) fed by a battery (2) at a predetermined nominal voltage (Ubat). According to the invention, the control step is preceded by a step of pre-magnetization of the open circuit stator in which an electromotive force of peak between phases substantially equal to the nominal voltage is created by a rotor excitation current (Ir) of a rotor (8) of the machine.
