摘要： A method for making a wound field for an electric motor, generator or alternator includes the steps of continuously winding an insulated conductor into a coil having a first plurality of windings wound in a first direction, and a second plurality of windings wound in a second direction opposite the first direction flattening the coil into a two-layered flat web, and rolling the flat, two-layered web end-to-end into a cylindrical configuration. In one embodiment, a multiphase wound field can be made by winding a plurality of insulated conductors about a common axis to form a group of adjacent coil units. After the first group of coil units is wound, second and subsequent groups can be wound, in alternating directions of winding with respect to the first group, to form an elongate winding assembly. The entire assembly, is then flattened and rolled end-to-end. This increases a wound field that is ready for insertion into a magnetic return path of an electric motor which has a higher density than was previously possible. As a result, current loss due to hysteresis and other features is materially reduced.

摘要： 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.
