A motor including an outside rotor having a rotor disc with plural magnets alternating polarities flush mounted in the disc, an inside stator assembly with a ring of pole pieces forming a channel to house a transversely wound stator windings, and a controller coupled with feedback electronics for monitoring a timing, speed and direction and coupling a signal to a processing unit for adjusting the drive electronics driving the phase windings. A u-shaped gap above the channel to receive the rotor disc and focus the captured magnetic flux in the pole pieces toward the magnets. In an embodiment the molded magnetic flux channel pole pieces of the inside stator are sets of molded magnetic flux channel pole pieces, each set forming a channel and corresponding to one phase of the motor; and a section of each one of the transverse windings passing through one channel, the remaining section folding back outside the set in close proximity to the outer base of the set of molded magnetic flux channel pole pieces.

I claim: 1. A parallel pole direct drive wheel motor comprising: an outside rotor having a rotor disc having plural holes around a circumference of the rotor disc a distance from an outer edge thereof with plural magnets having alternating polarities flush mounted into the plural holes;an inside stator assembly having a ring of plural molded magnetic flux channel pole pieces corresponding to a phase of the motor forming a hollow channel for housing a transversely wound stator windings to capture and focus magnetic flux emanating from the transverse winding and the hollow channel to the plural pole pieces, each pole piece body of the respective the plural pole pieces having a u-shaped gap above the hollow channel to receive the rotor disc, and said rotor plural magnets, with a gap therebetween; and, said each pole piece body formed with tapered exterior sides and radiused curves in a base of the u-shaped gap to direct and focus the captured magnetic flux toward and delivering the captured magnetic flux to axial magnetic pole flat surfaces with parallel sides of the u-shaped gap, perpendicular magnetic lines of force emanating at the pole piece surfaces; anda controller coupled with a feedback electronics for monitoring a timing, speed and direction and coupling the feedback signal to a processing unit for determining and adjusting and drive electronics to driving the phase windings.
