摘要： A method for manufacturing a laminated stator core for an electric motor includes providing a plurality of generally planar laminations, forming a plurality of notches into the lamination, and finally forming a plurality of interlock tabs. The notches extend outward from the interlock tabs to an outside diameter of the lamination to create a void in the back iron area of the interlock tabs to reduce the flux leakage.

摘要： An electrical current collector system includes a rotatable shaft (28); an electrically conductive slip ring (27); and a slip ring support assembly (42). The slip ring support assembly (42) comprises plural post insulators (102) spaced radially about the rotatable shaft for attaching the conductive slip ring to the rotatable shaft. The post insulators facilitate adjusting of the position of the slip ring relative to the rotatable shaft, e.g., to provide concentric positioning. The post insulators comprise an attachment/adjustment assembly (106) for connecting to the slip ring. In one embodiment, the attachment/adjustment assembly comprises a spring plate (134) which is adjustably biased to provide a preloading displacement that absorbs differential movement due to temperature changes of the slip ring an the rotatable shaft. In one example deployment, the current collector system is provided as part of a rotary transformer system (20) which, e.g., transfers electrical power between a first electrical system (e.g., first electrical grid) and a second electrical system (e.g., second electrical grid).

摘要： The invention relates to a spindle motor for hard disk drives with improved running accuracy where either the sheet metal package or the complete stator consisting of sheet metal package and windings is encompassed by a centering casing of plastic, which is preferably applied by means of an injection molding operation. Depending on the design of the spindle motor the centering casing can be centered on the stationary shaft and/or on the outer rings/inner raceways pertaining to the sets of rolling bodies. Furthermore, a stator without centering casing is described whose sheet metal package is centered directly on the outer rings/inner raceways.

摘要： A polyphase electric generator (10) is disclosed having a fixed output voltage configurable to virtually any voltage level within a certain range of voltages. The armature winding (18) of the generator is arranged in a combined Delta and Wye topology (60, 66). Each phase winding (20, 54) in the armature is partitioned into first and second sections of the phase winding (56, 58). The first sections (56, 62, 64) of each of the phase windings are arranged together in a Delta topology (60). Each of the second sections of each phase winding is arranged in a Wye topology (66) with a pair of the first winding sections. Each of the second sections (58) are connected at one end to a node (68) of the Delta topology where two of the first winding sections are connected. The opposite ends (70) of the second sections of each phase winding are connected to output terminals (26) of the armature to provide a line-to-line voltage output. The line-to-line output voltage (30) of the generator is dependent on the voltage across each winding phase (24) and the proportion of each phase winding arranged in a Delta topology.

摘要： A rotating electric machine with high-voltage stator winding and spring-device supporting the winding and method for manufacturing the same is employed for high-voltage applications. In particular, the machine includes a stator with a winding that is made of a high-voltage cable that is drawn through a slot in the stator of the rotating electric machine. A spring member biases the high-voltage cable against a wall of the stator so as to avoid damaging an outer surface of the cable during operation of the machine. The outer surface of the cable is susceptible to being damaged because an outer surface of the cable includes a semiconducting material that could possibly be damaged if subject to vibration or abrasion against a slot wall of the slot.
