Abstract
MP-T II Machines are alternating current, two, three, or four or more phase machines of the multipolar type, i.e. machines whose torque is produced in a cylindrical current tube through axially oriented current flow in a plurality of turns between pairs of parallel permanent magnet poles attached to cylindrical concentric magnet tubes. Unlike MP-T machines, MP-T II machines use flat permanent magnets and may contain cooling cuffs as needed.
Claims23
An electric machine comprising:
- multiple flat magnetic field sources surrounding at the outside and inside a current tube capable of conducting current;
- said current tube having a wall of substantially constant thickness;
- and said magnetic field sources establishing a magnetic flux density in a multiplicity of axially extended, regularly spaced zones in said current tube wall;
- and said magnetic flux density alternating in radial orientation between neighboring zones;
- and said current tube wall comprising at least one conductive elongated S-ribbon;
- said S-ribbon shaped so as to alternatively substantially overlap a multiplicity of adjacent zones and substantially overlap the gaps between said zones when the current tube rotates relative to said magnetic field sources.
A machine according to claim I wherein the current tube further comprises two or more concentric, mechanically fused but electrically insulated conductive layers,
