  • Patent number: 7315105
    Abstract: A device for axially magnetized electrical machines, especially motors, having a rotor with permanent magnets and a stator with a series of windings on iron cores. The stator comprises a support pin (17), which is integrated or joined with a protruding flange (20), which works as a support for cores (21, 22) with and without windings, which forms teeth. There are at least between some of the cores (21, 22) arranged support elements (25), which are fixed to the hub (18) of the stator.

  • Patent number: 6664692
    Abstract: A slow moving electrical machine includes an annular set of windings on iron cores of laminated sheets or pressed iron powder, and a corresponding annular set of permanent magnets, the windings being concentrated, and the iron cores having windings being arranged alternatingly with iron cores without windings. The machine has a number of grooves between the cores which is different from a number of poles of the permanent magnets, the number of grooves s and the number of poles p being defined by |s−p|=2*m and s=12*n*m, where n and m are natural numbers. The machine is constructed and arranged for three phase operation, with serial connection of adjacent windings within a group, with 2*m groups of windings per phase, and with serial or parallel connection of groups of windings.
