ELECTROMAGNETIC INDUCTION MACHINES

摘要

An electrical machine is described which has a first part comprising at least one assembly of insulated laminar conductors in which a pattern of current paths is defined and by which a plurality of alternating phase-related electric currents can be applied to produce a travelling magnetic field of regular alternating polarity. The electrical machine also has a second part comprising at least one electrical conductor closely adjacent to the first part and intersecting the travelling magnetic field. The second part is physically separated from the adjacent surface of the conductors of the first part by an air gap and is arranged to move with respect to the first part along the locus of the travelling magnetic field when the plurality of alternating phase-related electric currents are applied to the insulated laminar conductors of the first part. This structure permits new motor topologies to be provided which have advantages relating to robustness, low-cost, lightweight simplicity, reliability and efficiency.
