摘要： In a 4-pole, 6-slot, 18-segment electric motor, one forward winding coil (91) and two reverse winding coils (92, 93) are wound on each tooth (12). When the forward winding coils are formed of coils corresponding to a U phase, a V phase, and a W phase and the reverse winding coils are formed of coils corresponding to a “−U” phase, a “−V” phase, and a “−W” phase, the coils, which correspond to a U phase, a “−W” phase, a “−W” phase, a V phase, a “−U” phase, a “−U” phase, a W phase, a “−V” phase, and a “−V” phase, are electrically connected in this order between the adjacent segments. When the number of turns of the coils (91) corresponding to a U phase, a V phase, and a W phase is denoted by T1, the number of turns of the coils (92), which correspond to a “−U” phase, a “−V” phase, and a “−W” phase and first come into sliding contact with a brush, is denoted by T2, and the number of turns of the coils (93), which correspond to a “−U” phase, a “−V” phase, and a “−W” phase and later come into sliding contact with the brush, is denoted by T3, “T2>T1>T3” is satisfied.

摘要： The invention discloses an insulation system for a stator bar in high voltage electric machines, comprising an anti-corona tape that is wound uniformly and continuously over the entire length of a bare bar. The anti-corona tape comprises a thin resistive sublayer engaged to a thick insulative sublayer. The insulative sublayer provides resistance against high voltage. The resistive sublayer protects the insulation against partial discharges. These partial discharges can occur in voids, such as delamination voids, transposition crossover gaps, strand corners, slot voids, overlap voids etc. The resistive sublayer also increases the thermal conductivity hence reduces the operating temperature. Such insulation using a single-tape approach can replace several layers used in prior-art, viz., an internal corona protection layer, an external corona protection layer, a stress-grading layer and mica layers. This single-tape approach also simplifies the process of manufacturing the stator bar and reduces its cost.
摘要翻译： 本发明公开了一种用于高压电机中的定子棒的绝缘系统，包括在裸棒的整个长度上均匀且连续地卷绕的抗电晕带。 防电晕带包括接合到厚的绝缘子层的薄电阻子层。 绝缘子层提供高电压电阻。 电阻子层保护绝缘免受部分放电。 这些部分放电可以发生在空隙中，例如分层空隙，转置交叉间隙，线角，槽空隙，重叠空隙等。电阻子层还增加导热性，从而降低工作温度。 使用单带方法的这种绝缘可以代替现有技术中使用的几个层，即内部电晕保护层，外部电晕保护层，应力分级层和云母层。 这种单磁带方法也简化了制造定子线棒的过程，并降低了其成本。

摘要： Systems for harnessing power through electromagnetic induction utilizing printed coils are provided. A system can include one or more moveable magnets adjacent to printed coils on a circuit. For example, a system can include one or more magnets that are operative to move alongside a circuit board that includes printed coils. The one or more magnets may move, for example, when a user shakes the system or when the user walks or runs while holding the device. The movement of the one or more magnets may create an electromotive force (e.g., a voltage) across the printed coils, and this force may be used to generate electric power.
