Multi-tunnel electric motor/generator segment

A rotary motor/generator segment comprising:

• a toroidal magnetic cylinder comprising a plurality of magnetic tunnel segments radially arranged about a longitudinal axis to form a circular path, wherein the plurality of magnetic tunnel segments comprises at least:
• a first closed magnetic tunnel segment comprising:
• a first inner magnetic wall having a magnetic pole orientation that points generally towards an interior of the first closed magnetic tunnel segment;
• a first outer magnetic wall having a magnetic pole orientation that points generally towards the interior of the first closed magnetic tunnel segment, the first outer magnetic wall positioned farther from the longitudinal axis than the first inner magnetic wall;
• a first ring magnetic wall having a magnetic pole orientation that points generally towards the interior of the first closed magnetic tunnel segment and positioned to generally span a radial distance between the first inner magnetic wall and the first outer magnetic wall;
• a first opposing ring magnetic wall having a magnetic pole orientation that points generally towards the interior of the first closed magnetic tunnel segment and positioned to generally span the radial distance between the first inner magnetic wall and the first outer magnetic wall;
• wherein like magnetic poles of the first inner magnetic wall and the first ring magnetic wall are orientated in an opposite direction from the like poles of first outer magnetic wall and the first opposing ring magnetic wall;
• a second closed magnetic tunnel segment positioned circumferentially adjacent to the first magnetic tunnel segment, the second closed magnetic tunnel segment comprising:
• a second inner magnetic wall having a magnetic pole orientation that points generally towards an interior of the second closed magnetic tunnel segment;
• a second outer magnetic wall having a magnetic pole orientation that points generally towards the interior of the second closed magnetic tunnel segment, the second outer magnetic wall positioned farther from the longitudinal axis than the second inner magnetic wall;
• a second ring magnetic wall having a magnetic pole orientation that points generally towards the interior of the second closed magnetic tunnel segment and positioned to generally span a radial distance between the second inner magnetic wall and the second outer magnetic wall;
• a second opposing ring magnetic wall having a magnetic pole orientation that points generally towards the interior of the second closed magnetic tunnel segment and positioned to generally span the radial distance between the second inner magnetic wall and the second outer magnetic wall;
• wherein like magnetic poles of the second inner magnetic wall and the second ring magnetic wall are orientated in an opposite direction from the like poles of second outer magnetic wall and the second opposing ring magnetic wall;
• wherein the magnetic poles of the magnetic walls comprising the second closed magnetic tunnel segment are orientated in a direction opposite to the magnetic poles of the magnetic walls comprising the first closed magnetic tunnel segment;
• a coil assembly positioned within the circular path, the coil assembly comprising:
• a ring-like core;
• a plurality of teeth radially positioned about the ring-like core and extending from the ring-like core to form a plurality of slots;
• a plurality of coil windings wherein each coil winding in the plurality of winding is positioned within a slot within the plurality of slots.
