摘要： A motor-generator includes a rotor that rotates about an axis of rotation, and a stator that is stationary and magnetically interacts with the rotor. T'he rotor is constructed of two spaced apart rotor portions having magnetic poles that drive magnetic flux across an armature airgap formed therebetween. An armature, located in the armature airgap,has a substantially nonmagnetic and low electrical conductivity form onto which wire windings are wound. The form has a free end that extends inside the rotor, and a support end that attaches to the stationary portion of the motor-generator. The form is constructed with a thin backing portion and thicker raised portions extending from the backing portion in the direction of the magnetic flux. The wire windings have multiple individually insulated conductor wire. The conductors of a single wire are electrically connected together in parallel and electrically insulated between each other along their length inside the armature airgap. The wire windings are wound on to the form by inserting the wire to lie between the raised portions; the form provides position location and support for the wire windings during the winding process, and subsequently reacts the electromagnetically induced torque on the windings to the stationary portion of the motor-generator through the support end of the form and prevents the windings from contacting the rotor portions during rotation of the rotor.

摘要： A process for assembling a brushless motor-generator includes assembling a rotor formed from two spaced apart rotor portions having magnetic poles that drive magnetic flux circumferentially through the rotor portions and back and forth across an armature airgap formed between the rotor portions. An air core armature is formed by coating a substantially nonmagnetic armature form with a tacky adhesive layer, and winding armature windings into a winding pattern onto the substantially nonmagnetic form using wire made of multiple individually insulated conductor strands that are electrically connected in parallel but are electrically insulated from each other along their length when located inside the armature airgap, wherein the strands of said wire are diametrically held together by an outer serve. The winding of the armature form includes sequentially applying pressure to sections of said wire against the tacky adhesive layer.

摘要： An electronic motor drive for powering permanent magnet air core synchronous motors having sinusoidal back emf includes a switchmode power converter coupled to a connection of an input power supply. The power converter converts power from the input power supply with a current-mode control output and regulates current to a variable voltage link that supplies the regulated current to a non-modulating commutation inverter that energizes multi-phase air core armature windings of the air core motor. The motor drive employs 6-step position sensorless commutation exciting only two phase legs at a time controlled through measurement of the back emf. The switchmode power converter includes a low pass inductance and capacitance filter ahead of a power supply of the commutation inverter. The regulated current is switched at a regulation frequency high enough to preclude significant switching-induced harmonic ripple currents to the air core armature windings.

摘要： A slotless rotating electric machine includes a rotor having multiple alternating polarity permanent magnets that drive magnetic flux back and forth across a magnetic airgap formed with a radial airgap surface of a slotless ferromagnetic stator. The stator includes a helical backiron formed from a ferromagnetic strip wound edgewise and extending axially, and an adhesive film on the radial airgap surface of the backiron. Armature windings of wire having individually insulated twisted strands diametrically enveloped by an outer serve are adhered to the adhesive film. The adhesive film holds the said serve to the backiron and the serve holds the strands to the adhesive film. The armature windings are in an air core winding pattern formed directly onto the adhesive film in a one wire radial layer that is only one wire deep where inside the magnetic airgap, and having end turns of multiple phases overlapping. The armature windings pressed into said adhesive film as a group after they are formed and adhered while the adhesive cures, such that the wire is both bonded to said radial airgap surface of said helical stator backiron and is additionally partially embedded in the adhesive film.

摘要： An electronically commutated electric motor includes a rotor, a stator and an electronic drive. The rotor is journaled to rotate about an axis of rotation, the stator is stationary relative to the rotor, and the electronic drive provides synchronous power to the stator and drives the rotor. The rotor has two ferromagnetic radially spaced apart co-rotating rotor portions having a circumferential array of alternating polarity permanent magnet poles that drive magnetic flux back and forth across an armature air gap between said spaced apart rotor portions, and circumferentially through each of said rotor portions. The stator includes an air core armature supported in the armature airgap, and has a non-ferromagnetic structure where located in the magnetic flux in the armature air gap. Three phase windings wound on the armature magnetically exert torque upon the rotor when the windings are electrically energized by the electronic drive. The phase windings are wound from wire that is formed from bundled together multiple individually insulated conductor strands, wherein said strands are electrically connected in parallel and are electrically insulated between each other along their lengths where they lie in the magnetic flux in the armature airgap. The electronic drive is configured to convert electrical supply power into power that is synchronous with the rotor rotation by regulating power through a switch mode converter that varies voltage to a variable DC link supplying a transistor output H-bridge for commutating the phase windings. The electronic drive electrically energizes only two of the three phase windings simultaneously to provide trapezoidal excitation to the phase windings, leaving one of the three phase windings instantaneously electrically non-energized. The electronic drive monitors the instantaneous non-energized phase winding back-emf zero crossing events for controlling triggering of advances in the commutation.
