    摘要: An axial flux generator comprising: two magnetic annuli; a coil annulus; the magnetic annuli and coil annulus having a common axis; the two magnetic annuli defining a plurality of magnetic fields around the common axis extending across a gap between the two magnetic annuli and the coil annulus having a sequence of coils around the common axis in the gap such that the lines of magnetic flux from the magnetic fields cut the turns of the coils and this induces electric current in the coils as the magnetic annuli are caused to rotate relative to the coil annulus; wherein each coil has a shape in a plane perpendicular to the common axis where a first position and a second position on the shape are at a radial distance from the common axis that is greater than the radial distance from the common axis of a radially innermost position of the shape by an amount that is at least 60% of the difference in radial distance from the common axis between the radially innermost position and a radially outermost position of the shape and the first position and second position are on opposite sides of the shape at a radial location where the shape has a maximum dimension in a direction perpendicular to the radial direction, and a portion of the shape that is radially outward from the first and second positions is within an area bounded by an inner line and an outer line between the first and second positions, the inner line and the outer line both being radially outward from the first and second positions and having a radius that is 0.625 times the maximum dimension of the shape in the direction perpendicular to the radial direction, and the outer line being longer than the inner line.

    摘要: The invention relates to a device for winding/unwinding a link adapted to transporter a fluid or transmit energy and/or signals, comprising:



    a reel (2) adapted to receive said link in wound form,
    a hollow through shaft (3) adapted to the passage of said link or fluid between a rotating joint and the reel, said hollow shaft (3) being integral with the reel (2) in order to drive said reel in rotation about a longitudinal axis (X) of said shaft,
    at least one permanent magnet synchronous direct drive motor, comprising a stator carrying windings (10) adapted to be electrically three-phase powered and a rotor carrying the permanent magnets (11) facing windings (10) of the stator.
