  • Patent number: 9742231
    Abstract: A rotary electrical machine comprising a rotor and a stator (1). The stator comprises a tooth (21) delimited by notches (22), and a winding composed of n×M wires (3), wherein n corresponds to a number of phases and is equal to at least 2, and M corresponds to a number of continuous electric wires for each phase (3) and is equal to at least one. The winding is composed of successive turns, each of the successive turns comprising n×M wires wound simultaneously in n of the notches (22) to be inserted in n series of notches. Each of the series of the notches is dedicated to a single phase, and for each of the successive turns, each of the assembly of the M wires (3) constitutes a phase and is inserted in the same series of the notches (22).

  • Patent number: 8181332
    Abstract: A method of inserting an undulating winding into an alternator stator. The method comprises the following steps consisting of shaping each phase winding into a succession of crenels comprising two lateral branches which are intended to be attached at a position for reception in a slot, positioning the windings on an insertion tool and inserting the turns into the slots of the stator in the reverse order to the winding order. The windings are wound around the insertion tool simultaneously, and the turns that succeed one another in a determined winding order belong alternatively to different windings.
