ABSTRACT:
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.
