摘要： In an alternator stator for vehicle, each of the phase-windings includes first and second coil-end groups at opposite axial ends the stator core. Each of the slots includes radially aligned six layers. Each of the phase-windings comprises a plurality of sets of U-shaped segments disposed in a pair of slots separated from each other by a pole-pitch and a plurality of connection segments formed from the U-shaped segments. Each of the sets includes a large segment having a pair of the conductor members disposed in the innermost and the outermost layers, a medium segment having a pair of the conductor members disposed in the layers inside the innermost and the outermost layers to be surrounded by the large segment at the first coil-end group, a small segment having a pair of conductor members respectively disposed in the middle two layers to be surrounded by the medium segment at the first coil-end group. The small segment of one of the sets is connected in series with the small segment of another adjacent thereto at the second coil-end group to form a wave winding. The large segment of one of the sets is connected in series with the medium segment of another of the sets adjacent thereto at the second coil-end group to form a lap winding. The wave winding and the lap winding are connected in series by the connection segments to form one of the plurality of phase-windings.

摘要： A sequentially joined-segment coil for a rotary electric machine such an electric motor is provided. The coil has an end portion which is made up of heads of conductor segments and projects from an end of a core. The heads of conductor segments have turns or bulges. The bulges are lapped over one another in various forms or shifted in location in an axis direction of the core, thereby permitting the core to be decreased in diameter, which provides for decreases in size and weight of the rotary electrical machine.

摘要： An electric motor is provided with active hysteresis-based control of winding current. The motor has an efficient stator winding arrangement, as well as at least one adjustable air gap. Also provided is a stator, windings and air gap adjustment mechanism, as well as a method and system for controlling the torque produced by the motor using active hysteresis-based control of the motor's winding currents. The stator has its windings distributed among arc sections, the windings in each arc section being associated with only one phase of the motor. The hysteresis-based control of winding current is active in that a bandwidth or spread of the hysteresis band is adjusted depending on at least one of several selectively determined factors. The motor and its associated components are particularly well-suited for use in an electrically powered vehicle, as well as in hybrid vehicles using both electric power from a battery and electric power derived from a fuel-burning engine. A current detector is provided for generating outputs indicative of current flowing through each of three phase windings in a motor, based on detected magnitudes of current flowing through only two of the phase windings. Also provided is a discharge device for discharging residual voltage on a power bus of an electric vehicle.

摘要： Known turn-to-turn windings with overlapping conductor lanes either only insufficiently use the groove space or are difficult to produce. In addition, uniform distribution of current density is not achieved in the winding overhang space. The disclosed multiple phase conductor layers are made of identical conductor lanes located in the groove space at the same distance from the air gap surface. The conductor layers stacked in the grooves complement each other in the use of the winding overhang space in that they lead the current in opposite directions across the width of the groove. Uniform distribution of current density and high space utilization are achieved in that the layered winding overhangs are offset in relation to the layers in the grooves in direction of the groove depth by one half the height of a layer. Each conductor lane occupies two winding overhang layers when passing through the winding overhangs, the transition between layers taking place at about the middle of the middle of the connection section at the outside of the winding overhangs. The conductor layers once removed are connected with each other. Motors and generators equipped with space-optimized turn-to-turn windings are characterized by high efficiency and power density.
摘要翻译：具有重叠导体通道的已知的匝间绕组仅仅不足以使用凹槽空间或难以制造。此外，在卷绕悬垂空间中不能实现电流密度的均匀分布。公开的多相导体层由与空隙表面相同的距离位于凹槽空间中的相同导体通道制成。堆叠在槽中的导体层在卷绕悬空空间的使用中彼此互补，因为它们跨越沟槽的宽度在相反方向引导电流。实现了电流密度均匀分布和空间利用率高，其中分层绕组突出端相对于沟槽深度方向上的层相对于层的高度偏移一半。每个导体通道在通过绕组突出端时占据两个绕组突出层，层之间的过渡在连接部分的中间的中间位于绕组突出部的外侧。一旦去除的导体层彼此连接。配有空间优化的匝间绕组的电机和发电机的特点是效率高，功率密度高。

Each single-phase winding portion has two wave windings formed by winding a conductor wire for a predetermined number of winds into a wave-shaped pattern composed of slot-housed portions disposed at a pitch of six slots in a circumferential direction and crossover portions linking together end portions of adjacent pairs of the slot-housed portions alternately relative to an axial direction, the wave windings being offset by six slots from each other circumferentially and installed in the slots such that the crossover portions face each other axially.
