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.

A brushless dc motor, comprising: means for generating high-intensity, substantially unidirectional magnetic field lines between at least one pair of adjacent opposing magnetic poles; and a plurality of coils mounted in a substantially electrically non-conductive environment closely juxtaposed to said generating means, and adapted to intersect said magnetic field lines at points of substantially maximum strength thereby minimizing electrical losses, each said coil having a width that is substantially equal to a distance said adjacent opposing poles; wherein said means for generating said magnetic field lines and said plurality of coils are mounted for relative motion about an axis of rotation, and wherein said magnetic field lines being generated are substantially parallel to said axis of rotation.
