Patent ID: 7579742

Claim:
A high efficiency direct drive high torque motor comprising: a non-rotating mounting shaft having a hollow channel and a bearing attached to each end of the mounting shaft; a cylindrical non-rotating hub having a hollow core for the non rotating mounting shaft; plural rows of adjacent plural Parallel Pole Molded Magnetic Flux Channels separated by a gap, each parallel pole molded magnetic flux channel consisting of a north pole piece and a south pole piece, a top portion of each pole piece having a width less than the width of a base portion and a length approximately double the length of the base portion for an approximately equal cross sectional area to decrease magnetic flux leakage and fringing, the north pole piece and a south pole piece mate to form a hollow winding channel, the plural parallel pole molded magnetic flux channels fixedly attached on a cylindrical surface of the cylindrical hub, each row of plural parallel pole molded magnetic flux channels corresponding to one phase of the motor to increase magnetic flux and magnetic flux area for increasing torque; a phase transverse winding passing through the row of plural parallel pole magnetic flux channels forming a stator corresponding to the phase to reduce inductive loss; a rotating drum having plural rows permanent magnets on an inner surface, each row corresponding to and aligned with one row of parallel pole molded magnetic flux channels, the rotating drum connected with the bearing to allow the row of permanent magnets to rotate around the cylindrical hub; and drive electronics for driving the phase winding by supplying an alternating current when the current through the transverse winding reverses, the magnetic polarity of the mated north and south pole pieces switch, wherein the plural molded magnetic flux channels are timed to increase torque and motor efficiency of the direct drive motor.
