摘要： An electric machine rotor includes a rotor body configured to rotate about a rotation axis. A winding includes a plurality of end winding portions extending circumferentially over an axial end of the pole core. An anchor is woven into the end winding portions to inhibit movement of the end winding portions relative to the pole core. The anchor includes a first portion extending radially outward along a first row of the end winding portions. A second portion of the anchor extends axially from the first row, beyond a second row of the end winding portions to a third row of the end winding portions. A third portion of the anchor extends radially along the third row. A fourth portion extends axially between two of the end windings in the third row. A fifth portion of the anchor extends radially inward between the second row and the third row.

摘要： A rotary electrical machine includes a stator and a rotor. The stator includes a plurality of iron cores that are annularly disposed, windings that are wound to each of the plurality of iron cores, connection terminals to which the windings are connected to, and molded members that partially cover the plurality of iron cores and the windings. The rotor rotates around an axis that coincides with a circular center of the plurality of iron cores. The molded members have resin portions that cover the plurality of iron cores and the windings, and a plurality of exposed terminal portions that expose the connection terminals.

摘要： An electric motor as well as a manufacturing method for the electric motor and a manufacturing tool are provided, the electric motor being for a deep well vertical turbine pump and having a stator assembly that has a stator bore to hold a rotor and slots that are radially open to the inside, respectively separated from each other by a stator tooth, and in which electrical conductors made of round wire of coils of a coil assembly lie, with the distributed windings on one axial end of the coil assembly forming a winding head in which the coils are encapsulated. The winding head only extends between an inner diameter and an outer diameter which is smaller than the diameter of the stator bore in which the coil assembly is inserted axially into the slots of the stator assembly.

摘要： A tooth-wound coil of a stator or of a stator segment of a dynamo-electric machine having two straight sections spaced apart from each other and running substantially parallel. Two 180° curves are located on the ends thereof, wherein the straight sections have an active part area, the axial extend of which is less than or equal to that of the straight section. The tooth-wound coil has a symmetrical extension plane running in the longitudinal direction. An insulation material is provided around the straight sections of the tooth-wound coil. The material effects groove isolation and/or phase isolation in the stator or stator segment.

摘要： A stator core comprises a stack and a resin portion. The stack comprises an annular yoke portion, a plurality of tooth portions, and a plurality of slots. The resin portion covers an inner wall surface of a slot of the plurality of slots. The resin portion protrudes outward relative to an end surface of the stack in a height direction of the stack. The resin portion is formed on at least a part of an end surface of the tooth portion so as to extend from the inner wall surface of the slot around the end surface of the tooth portion. A resin end portion of the resin portion is disposed on the end surface of the stack and a corner of the resin end portion is formed as an inclined surface including a planar surface or curved surface.

摘要： A method for producing a wire coil. Multiple windings of a ply of the wire coil including an insulated wire are wound onto a coil core of the wire core starting from a first winding up to a last winding. The last winding is hooked in an electrically insulating deflection hook of the wire coil which is fixed with respect to the coil core and the wire is deflected by the deflection hook.
