Abstract
A rotating electrical machine including a first member (10) capable of generating a magnetic field which rotates relative to the first member, and a second member (6) which is provided with a winding through which a current can flow, such that the rotating magnetic field drives the second member in rotation. An electrical value which is at least related to the current is measured (18) and the generation of the rotating magnetic field is started (12) at a time which is determined as a function of the electrical value which is measured. A method of controlling the machine is also disclosed.
