  • 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: 9016610
    Abstract: A method and device for winding a rotor or a stator (2), of a rotary electrical machine, having a series of teeth (21) which are delimited by notches (22). In each notch there are inserted M continuous electric wires (3) constituting a turn; M being equal to 1 or more, characterised in that n×M wires (3) are wound simultaneously in a number n of notches (22), n corresponding to the number of phases and being ?2. The assembly of the M wires (3) constituting a phase, being inserted in a single notch (22). The device for winding has at least two carriages (4, 5), with a series of teeth, delimited by n notches (40, 50). And, likewise corresponding to the winding, each set of M continuous electric wires (3) constituting a turn, is characterised in that M×n wires (3) are inserted simultaneously in the extension of the n notches (22) of the rotary electrical machine in the n notches (40, 50) in the respective carriages (4, 5).

  • Publication number: 20070100386
    Abstract: The disclosure describes an axial lead connector assembly for an implantable medical device (IMD). The lead connector assembly facilitates electrical connection between an implantable medical lead and circuitry contained within the housing of an IMD. A connector header defines an axial stack bore to receive an axial stack of in-line connector components. The connector components define a common lead bore to receive a proximal end of an implantable lead. The in-line stack of connector components may include seals, electrical connector elements, a strain relief, and a locking device, each of which defines a passage that forms part of the lead bore.
