摘要： An iron core including a laminate of a plurality of fixed electromagnetic steel sheets, a laminate of alloy thin strips which is sandwiched between the laminate of the electromagnetic steel sheets, a fastening mechanism which penetrates the laminates of electromagnetic steel sheets and alloy thin strips, and a fixing base. The laminate of alloy thin strips reduces compressive and torsional forces acting on the laminate of alloy thin strips by using the iron core having a structure in which upper and lower portions of a laminate of alloy thin strips having nanocrystal grains are sandwiched together with laminates of amorphous alloy thin strips. Furthermore, a motor including a rotor and the above-described iron core is used.

摘要： An embodiment provides a stator core including a plurality of first single teeth, a plurality of second single teeth and coils. The teeth are I-shaped and each have a long side, a short side, a connection portion and a wire-accommodating slot located on the sides of the connection portion. The coils are wound around the connection portions and accommodated in the wire-accommodating slots. The stator core is an annular element formed by splicing first single teeth and second single teeth in sequence in a staggered manner into a circle, and winding modes of the coils on the first single teeth and the second single teeth are different, so that the contour of the coils located on the outer side of the wire-accommodating slots of the first single teeth is different from the contour of the coils located on the outer side of the wire-accommodating slots of the second single teeth.

摘要： An electric motor has a first carrier having an array of electromagnetic elements and a second carrier having electromagnetic elements defining magnetic poles. The first and second carriers each define an axis. An airgap is formed between the first and second carriers when in an operational position. An inner thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. An outer thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. The electromagnetic elements of each of the first and second carriers are arranged radially inward of the outer thrust bearing and radially outward of the inner thrust bearing. The inner thrust bearing and the outer thrust bearing are arranged to maintain the airgap against a magnetic attraction of the electromagnetic elements of the first and second carriers.

摘要： A stator of an electrical machine which has stator slots and conductor elements arranged in the stator slots, which conductor elements each have two conductor ends, is already known. A plurality of conductor ends, which are situated next to one another, of different conductor elements are in each case connected to one another by means of a weld connection, which is provided at the end sides of the conductor ends in question, without additional material. The conductor ends which are connected to one another in each case form a common rectangular conductor cross section which has a height H and a width B, wherein the height H corresponds to the height h of an individual cross section of the conductor ends, and the width B of the common conductor cross section is made up of the sum of the widths b of the individual cross sections of the conductor ends. The weld connection is in each case provided, as seen in the direction of the width B, between two non-melted edge sections of the outermost conductor ends. The weld cross section in the direction of the height H is comparatively low, this having effects on the long-tem mechanical strength of the weld connection and, during operation of the electrical machine, possibly causing temperature peaks at the weld connection as a result of a high current density. In the case of the stator according to the invention, the mechanical strength of the weld connection is increased. According to the invention, it is provided that the extent (L2) of the weld connection (8) in the direction of the height (H) is greater, at least in sections, than the height (H) of the common conductor cross section (9), and the surface of the weld connection (8) is consequently sunken in relation to the end sides (6) of the edge sections (10).

摘要： A rotating electric machine includes a stator and a rotor. The stator includes a stator core and a stator winding that includes phase coils wound around slots of the stator core. Each phase coil is configured such that: a first end is connected to an external terminal; a second end is connected to a neutral point; and 2n (n being a natural number) circling coils are arranged to circle the stator core and connected in series. A neutral-point-side coil is housed in a first slot where a terminal-side coil is housed. The terminal-side coil is a circling coil that is arranged on the external-terminal side of a first phase coil among the phase coils. The neutral-point-side coil is a circling coil that is arranged on the neutral-point side of a second phase coil among the phase coils. The second phase coil is different in phase from the first phase coil.
