摘要： PROBLEM TO BE SOLVED: To make the manufacture of a rotor coil device of a single-pole electric rotating machine easy and lessen the number of processes and reduce the manufacturing cost by forming conductors in thick magnetic flux sections with magnetic substance and forming conductors in thin magnetic flux sections with non-magnetic substance. SOLUTION: In correspondence with many poles, windings b11, b12, etc., of thick magnetic flux sections b11, b12 are formed with iron or other magnetic substance similar to iron. Windings a11, a12, etc., of thin magnetic flux sections a11, a12 serially connected to the thick magnetic flux section are formed with non-magnetic substance such as copper and aluminum. The values of the voltages V2, V4 generated by the thick magnetic flux sections b11, b12 are large and the voltages V1, V3 generated in the thin magnetic flux sections a11, a12 are weakly induced and the directions are opposite to those of the V2, V4. Therefore, the final induced voltage V appearing across the conductor is expressed by V=(V2+V4)-(V1+V3).

摘要： The invention relates to a single-phase or multiple-phase AC machine which is energised in a homopolar fashion and has at least two stator laminate stacks (2 to 4), which are arranged axially one behind the other in a magnetically conductive housing (1) and are provided with a stator winding (12), as well as a rotor which is divided into axial regions which are allocated to the stator laminate stacks (2 to 4) and have zones of different magnetic reluctance with respect to the stator laminate stacks (2 to 4) on their circumference, and in which machine energising takes places at least partially by means of permanent magnets which are arranged in the stator. In order to reduce the influence of the armature reaction and as far as possible to prevent the formation of eddy currents in the rotor, permanent magnets (14 to 16) are arranged in a cylindrical shape on the bore surface of the individual stator laminate stacks (2 to 4). These permanent magnets (14 to 16) are magnetised in the same sense, seen in the circumferential direction, as each stator laminate stack (2 and 4 or 3 respectively) but in the opposite sense with respect to the respectively adjacent stator laminate stack (2 and 4 or 3 and 4 respectively).

摘要： A synchronous machine having a stator which has a laminate stack with slots in which a stator winding is located. A rotor is constructed as a rotor with poles, and means are provided for essentially uniform magnetisation of the poles of the rotor in operation. The magnetisation means are constructed such that the ends of the poles of the rotor facing the laminate stack of the stator are magnetised in the same polarity in operation. In consequence it is possible for the magnetisation means to be arranged outside the rotor and they may even be stationary so that more space is available for a larger volume of permanent magnets. The rotor can be constructed very easily and is suitable for very high speeds. The efficiency of the machine is improved. (Drawing Fig. 1).

摘要： The homopolar generator has at least two stator lamination packs mounted axially behind each other in a magnetic casing and carrying a stator winding, and a rotor divided in parts corresponding to the lamination packs. They have zones of different permeability. Radially magnetised permanent magnets (5) are between the lamination packs (2-4) and the casing (1). Their polarities in adjacent packs are opposite to each other. A stator winding (14) surrounds all the lamination packs (2-4), and rotor zones of equal permeability are spaced by angles corresponding to the stator winding pitch.

摘要： 619,837. Permanent magnet machines. MANDL, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 31, 1946, No. 38140. [Class 35] In a permanent magnet homopolar A.C. machine, the field members at each end of the permanent magnet have members providing a flux leakage path across an air-gap in parallel with the working flux circuit, and means are provided for closing this air-gap, the permanent magnet being magnetized in situ by means of a magnetizing winding. In the generator shown, the magnet 10, which may be of cylindrical form, or may be built up of a series of parallel bar-magnets, is located between yoke members 4, 7 which carry the flux to the rotor 1 and also through extending parts 8. 9, having flanges 13, 14, across the leakage air-gap 15. The rotor 1 comprises a toothed portion 2 co-operating with a laminated stator core 5 having output windings 6. The flux return path is by means of a small annular air-gap between an enlarged cylindrical flange 3 and the inner surface of the member 7. The magnetizing winding 16 is located concentrically round the magnet and before use the gap 15'is bridged by a magnetic ring. After magnetizing, this ring is replaced by a non-magnetic cover 24, so that the flux falls to a steady value, and the rotor placed in position. By this arrangement, removal of the rotor does not disturb the flux of the machine. A damping ring may be placed concentrically within the magnet. In a modification, the cylindrical air gap 3, 7 may be replaced by a further laminated stator core and corresponding rotor teeth, and the leakage gap may be closeable by adjustable means such as a screwed sleeve which may be used for automatic regulation of the machine output. The machine may alternatively have a permanent magnet rotor.

摘要： 273,908. Cardellino, M. M. July 21, 1926. Magneto-electric machines.-In an ignition magneto having a tubular magnet, the armature has a high tension winding disposed between cores in such a manner that the flux closes alternately inside and outside the coil. Figs. 7, 8 show a machine for producing eight sparks per revolution. The magnet 1 is provided with polepieces 2, 2' at each end and the rotor comprises a laminated core 6 carrying a single winding 10 and having laminated pole-pieces 7, 7 at each end. The co-operating pole-pieces 2, 7 and 2 , 7 have an equal number of projections and between the rotor pole-pieces are disposed laminated bars 9 extending along the whole length of the rotor outside the coil. The space between the bars and the pole-pieces is preferably filled with insulating material 8. The flux closes alternately through the bars 9 and through the circuit comprising the pole-pieces 7, 7' and the core 6. One end of the generating coil is earthed and the other is connected to electrodes 11 from which current is collected by fixed contacts 14 arranged in one or more parallel planes. Specification 232,573 is referred to.
