ABSTRACT:
A DC motor particularly adapted to operate in the presence of translational movement between the armature (rotor) and the field (stator) magnets. The field magnets comprise a plurality of magnets formed into a pair of concentric, closed-spaced, parallel rings mounted to rings of soft, magnetic material. The armature is a planar armature wound in a serpentine pattern so as to cross back and form between the rings only on radial lines from a center point on the armature. The radial conductor lines are sized with respect to the width of the magnetic ring such that even in the presence of translational motion, only the radial conductors cross between the rings and the motor can continue to operate.
