Abstract
A brushless dc motor, suitable for use as a hand-held surgical tool, includes a plurality of coils arranged in a substantially electrically non-conductive environment closely juxtaposed to a plurality of magnets which generate high-intensity, substantially unidirectional magnetic field lines such that the plurality of coils intersect the magnetic field lines at points of substantially maximum strength in order to minimize electrical losses.
