A winding for an active portion of a rotary electric machine has at least one phase system including a plurality of phases each including a first energizing pin and a second energizing pin each forming a phase input or output. Each energizing pin includes an energizing end that extends out of the slot and each energizing end that forms a phase output being electrically connected to an energizing end that forms a phase input of a different phase, in order to achieve a delta configuration. The winding includes a first set including at least one energizing end forming a phase input and at least one other energizing end forming a phase output, and a second set including at least one energizing end forming a phase input and at least one other energizing end forming a phase output.

Electrical winding for a rotating electrical machine

The method of control according to the invention slaves a DC voltage generated by the alternator to a predetermined setpoint value by controlling an excitation current flowing in an excitation circuit comprising an excitation winding of a rotor of the alternator. The excitation current is controlled by means of a semiconductor switch, in turn controlled by a control signal having a predetermined period. The method comprises a detection of a failure of the excitation circuit. At least one short-circuit of the excitation winding is detected. According to another characteristic of the method, the control signal is generated on the basis of a combination of a setpoint signal formed by pulses of the predetermined period exhibiting a duty ratio representative of the setpoint value and of a detection signal indicative of the short-circuit.
