ABSTRACT:
A brushless D.C. motor, suitable for use as a hand-held surgical tool, includes a field of self-supporting coils arranged between a pair of impregnated fiberglass epoxy sheets situated in an air gap formed by a rotatable shaft having an even-number plurality of magnets formed thereon, and a non-electrically conductive housing. The individual magnets abut one another upon the shaft to prevent a magnetic return path from the substantially unidirectional field produced thereby, and are formed in relationship to the coils such that a single rotor pole will never be under a single coil, in order to minimize induced shorted currents.
