A regulating module for a rotary electric machine having an operating mode in which a battery of the vehicle is disconnected. The regulating module includes a rotor module and a stator module. The rotor module is arranged to generate a first intermediate setpoint (I_RotRef) on the basis of which is generated the first output quantity (V_Rot) for controlling the rotor, said first intermediate setpoint being determined on the basis of a power potential reference signal (Pdc_MaxRef) and of a speed of rotation (W) of the rotor and being independent of a power or of a control torque of the machine. The stator module is arranged to generate a second intermediate setpoint on the basis of which is generated the second output quantity for controlling the stator, said second intermediate setpoint being determined on the basis of the output voltage of the machine.

Regulating module for a rotary electric machine

The method for controlling a rotating electric machine according to the invention comprises a step of controlling the phase currents of the machine by means of a full-wave control (C). According to the invention, the full-wave control (C) is generated via a pulse width modulated signal of which the signal frequency is greater than an electric frequency of the machine. According to another feature, ascending or descending fronts () of the pulse width modulated signal are synchronised with first and second crossings of first and second angular switching thresholds (S, S) by an electric position (&#x3b8;) of the machine and a duty ratio (&#x3b1;) of the pulse width modulated signal is periodically refreshed to the signal frequency.

The inventive method is of the type of those comprising a control stage for driving mode operation of the machine () in which currents of the phases in phase windings (u, v, w) of a stator () of the machine, which is connected to an on-board power system () supplied by a battery () providing a predetermined nominal voltage (Ubat), is 'full wave' controlled. In accordance with the invention, the control stage is preceded by a pre-magnetizing stage of the stator in open circuit, in which an electromotive peak force between phases substantially equal to the nominal voltage is created by a rotor excitation current (Ir) of a rotor () of the machine.

The invention relates to an architecture which is applied to a six-phase rotary electric machine of the type comprising first and second three-phase systems offset angularly at a predetermined offset angle. First and second phase windings of the three-phase systems respectively carry first (U, V, W) and second (U, V, W) phase currents controlled by electronic power modules (). The electronic modules comprise first and second power terminals () each capable of being electrically connected to first and second instances of the first and second phase windings. According to the invention, the electronic power modules are interconnected such as to balance the losses.

A rotary electrical machine comprises a rotor including a plurality of poles and a plurality of windings (E-E) wound about the poles, a stator, and a compensation device configured to compensate the armature magnetic reaction of the stator. The compensation device comprises at least one permanent compensation magnet which is implanted in a pole(s) of the rotor. The magnet(s) is/are sized and placed in accord with the desired compensation effect desired.

Rotary electric machine with armature magnetic reaction compensation

A method for determining the position at rest of a rotor of a machine having at least one excitation winding. The invention provides a technique for detecting the position of the rotor at rest, from information contained in the voltages produced at the terminals of the stator windings, when the voltage applied to the rotor winding undergoes variations. The invention thus makes it possible to detect the rest position of the wound-rotor machine in the absence of ordinary position sensors such as magnetic, optical, resolving, mechanical, capacitive or other sensors.
