摘要： A stator structure for a motor of high precision by suppressing influence of electromagnetic noise between windings and a distribution pattern layer in a printed board. A shield is provided between the windings and the distribution pattern layer of the printed board to shield the electromagnetic noise and suppress the influence of the electromagnetic noise to thereby enable precise control of the motor. A multilayered printed board is arranged on an axial end face of the stator core and the windings are formed around the stator core and the multilayered printed board to enfold them toroidally in a regular winding manner. The multilayered printed board comprises a distribution pattern layer for connection with the windings and a shield layer for shielding electromagnetism between the distribution pattern layer and the windings.

摘要： A method and structure for restricting relative sliding motion at the interfaces between a superconducting winding and a supporting structure for the winding. An interface lining material having a low shear modulus of elasticity so as to accommodate large shear displacements with low shear stresses is used as opposed to the use of sliding frictional contact between the contacting surfaces of the electrical winding and the supporting structure. The invention is completed by subjecting the lined interfaced surfaces to large compressional pressure forces so that frictional forces between the interface material and the opposing superconducting winding and supporting structure surfaces, even at low coefficients of friction, are considerably higher than the internal shear forces of the interfacing lining material. The superconducting winding is comprised of a plurality of conductors of superconducting material bunched together in close thermal contact with each other and secured in a solid winding bundle by epoxy resin. The interface lining material preferably is wrapped completely around and surrounds the superconducting winding.

摘要： This invention relates to an improved wire wound disc type armature for electric motors or generators. The armature has a disc shaped body mounted on a central shaft with a commutator formed of spaced insulated commutator elements located around it. The disc shaped body has opposing flat sides on which a predetermined number of wire windings are located. The insulated wire forming each winding extends outward from the commutator through a U-shaped wire channel on one side of the disc shaped armature and back through a corresponding wire channel on the other side. The disc shaped body of the armature is formed of high strength plastic and the wire channels are formed of laminated steel. In one embodiment, the wire then passes through an aperture in the disc shaped body associated with each winding and back out through the first wire channel and this is repeated until a winding of a desired number of turns is formed in the two channels. This structure and winding configuration provides the significant advantage that the amount of wire used which does not pass through the magnetic field during use is kept to a minimum. This reduces initial wire costs and more significantly, decreases heat and other losses which otherwise occurs in the excess wire, as well as minimizes interference currents which may be induced on current reversals.

The troughs may have cover plates also having side walls extending into the stator slots, and the troughs with the windings therein form a cylindrical structure in the air gap. This structure can be held in position closely adjacent the stator core by conformable packing or wedges associated with the side walls of the troughs and the stator slots.
