  • Publication number: 20080203848
    Abstract: The present invention relates to an electrical multipole motor/generator or electrical machine with axial magnetic flux, wherein the machine has a number of stator pole cores being larger than the number of rotor pole shoes. Thus, a motor/generator or electrical machine is provided in which the machine comprises a rotor secured to a shaft with an axis of rotation, where the rotor comprises magnets or means for producing a magnetic field and a number set to N of pole shoes. The machine further comprises a first stator with air gaps formed between the rotor and the first stator, where the first stator comprises a number set to M of separate pole cores or pole legs having corresponding separate coils or set of windings wound on and surrounding said pole cores or pole legs, wherein N and M are larger than one and M is larger than N. N may be an equal number, and M may be equal to 2N, or M may be equal to 3N, or M may be equal to 4N.

  • Patent number: 6844656
    Abstract: This invention relates to an electric multiple motor/generator with axial magnetic flux. Thus a generator/motor or electrical machine in which a magnetic flux path through one or more pole legs or pole cores surrounded by current windings or coils is provided. This allows a high density of the magnetic flux to be passed through the pole legs or cores, which results in a low consumption of material for the pole legs or pole cores compared with prior art machines, where for example a large stator diameter may be needed in order to conduct a high magnetic flux. Additionally the generator/motor or electrical machine is very efficient both at a low and a high number of revolutions. According to another aspect of the invention a multiple phase output without enlarging the diameter of the generator is provided.
