摘要： A segment center line is defined for each segment. Each segment center line extends from the center in the circumferential direction of the radially outer end of the segment to the center in the circumferential direction of the radially inner end of the segment. A portion of each segment center line where there is the center in the circumferential direction of the radially inner end is inclined in a first circumferential direction relative to the radial line. A short-circuit member has a plurality of connection pieces. Each connection piece has an outer short-circuit end, an inner short-circuit end, and a coupling portion. Each coupling portion links the outer short-circuit end to the inner short-circuit end, which is shifted in a second circumferential direction from the outer short-circuit end.

摘要： A dynamoelectric machine commutator structure having a plurality of conductive commutator segments secured in operating position by a commutator banding is characterized by including a flexible, thermally stable dielectric coating material between the outer edges of the commutator banding and the conductor segments in order to effectively seal the junction between those members, thereby preventing the deposit or buildup of electrically conductive contaminants at that junction so that the likelihood of electrically short circuiting the conductive segments of the commutator is effectively eliminated. According to the preferred method of the invention, a banded commutator is formed by applying such a coating to predetermined portions of the banding grooves so that the coating effectively seals the junctions between the banding and the conductive segments of the commutator, thereby preventing the accumulation of conductive contaminants at those junctions. In one embodiment a release layer is provided on the side of the coating facing the commutator banding in order to establish the junction between the banding and the release layer as the most preferred site of any contaminant-collecting fissures that may be created by relative movement between the banding and the commutator segments.
摘要翻译：具有通过换向器扎带固定在操作位置的多个导电换向器段的电动机换向器结构的特征在于在换向器条带的外边缘和导体段之间包括柔性的，热稳定的介电涂层材料，以便有效地密封连接处，从而防止在该结处导电污染物的沉积或积聚，从而有效地消除了换向器的导电段的电短路的可能性。根据本发明的优选方法，通过将这种涂层施加到条带槽的预定部分上形成带状换向器，使得涂层有效地密封换向器的条带和导电段之间的接合，从而防止在这些路口有导电污染物。在一个实施例中，剥离层设置在面向换向器条带的涂层侧上，以便建立条带和剥离层之间的连接点，作为任何污染物收集裂缝的最优选位置，其可以通过相对运动条带和整流子片段。
