Abstract: A stator (2) for use in a slotless electric motor (1), particularly an electronically commutated motor, has a winding body (21) in the form of a hollow cylinder, consisting of three or more coils (26), and having a working section (15) located between two winding heads (23, 23′) at two longitudinal ends of the winding body (21), and a cylindrical stator lamination stack (22), close-fittingly encompassing said working section (15) of the winding body (21). The two winding heads (23) consist of the longitudinal ends (28) of the three or more coils (26). They positively lock the stator lamination stack (22) along a longitudinal axis (19) of the winding body (21). The two winding heads (23) have the shape of a circular flange with an inner radius (rwh) essentially equal to an inner radius (rws) of the working section (15) of the winding body (21).

Abstract: A lightweight superconducting machine suitable for aerospace applications provides a wound-field rotor suspended from a driveshaft by insulating tensile spokes. The resultant reduction in heat transmission allows a cryocooler positioned centrally within the rotor to cool the machine coils through radially conducting straps.

Abstract: A displacement sensor has a magnetic measuring transducer and at least two sensor units, which are arranged at different positions spaced from each other, the measuring transducer being slidably mounted relative to the sensor units. The measuring transducer is magnetized such that it has a magnetic field which rotates at least partially about an axis of rotation along the measuring transducer, and the axis of rotation of the magnetic field runs parallel to the sliding direction of the measuring transducer. The sensor units are designed to each sense two magnetic measured variables proportionally to the magnetic field strength, both measured variables being sensed by both sensor units.

Abstract: A manufacturing apparatus of an electrical rotating machine includes a coil segment shaping section for shaping a linear wire rod with a predetermined length into a coil segment with a predetermined shape consisting of a pair of slot insertion portions extending substantially in parallel with each other and a linking portion for coupling the pair of slot insertion portions, and a coil assembling section for assembling a coil by circularly arranging the coil segments shaped in the coil segment shaping section. The coil segment shaping section and the coil assembling section are constituted to continuously perform the shaping and the assembling of the coil segment in each coil segment unit, based on control data set depending on a coil to be fabricated.

Abstract: A path sensor includes: a sensing device; at least two sensor units assigned to the sensing device, wherein the sensing device can be displaced relative to the sensor units and has a property changing at least once from a starting value to an end value along the sensing device, which property can be detected by the sensor units; and an evaluation unit, which is designed to determine the position of the sensing device relative to the sensor units as a function of the property values detected by the sensor units. The sensing device has at least two sections following on from one another in the direction of movement, along which sections the property changes from at least the starting value to at least the end value, wherein the change has different gradients in the sections.

Abstract: 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.
