Abstract
A machine having a wound rotor (102) comprising a manifold (112) that includes a set of blades (131) and longitudinal notches (133). Rotor (102) also comprises a winding (108) formed of a set of conductors (134) that each comprise two arms (135.1, 135.2), connected together by a base (136). The curve, representing the electromotive force (EMF) generated by the rotor (102) on the basis of the angle of rotation of the rotor, is linear and steep in a switching region, and the notches (133) are angularly shifted relative to the blades (131) so that each notch (133) is located opposite a junction between two blades. The machine may relate to a starter fitted with the machine.
