    摘要： The rotor body of an electrical machine has end windings (50) supported by a plurality of circumferentially spaced rakes (58) having tines between which the end windings pass in an arcuate pattern from and for return to an axial orientation within the rotor body. The rakes are supported on axial beams (56) secured to the rotor body. An end disk (52) is secured at the opposite ends of the beams and to a shield (72) overlying the end windings. The rakes, beams and end disks provide axial end winding restraint. The end disk is weighted at selected circumferential locations to resist tendencies of the end windings to distort, e.g., toward an elliptical or non-concentric configuration about the rotor axis.

    摘要： A method and apparatus for production of stator windings for dynamoelectric mechines of different configurations is provided. The windings are preferably formed on a bobbin (10) or similar article, which may then be transferred onto an appropriate carrier such as a ferromagnetic core (24). The core (24) may be provided as a substantial linear article and then be bent into an appropriate shape, so that the assembly may be provided as the stator of a dynamoelectric machine. In this configuration, only a portion of each winding will face the magnetic poles of the rotor and thus be operative, as the return path of the windings will not be used. However, the invention as disclosed also shows it is possible to build a drum rotor (39) with both external and internal rotors in order to make use of both portions of the windings on the ferromagnetic core (24).

    摘要： An electro-mechanical machine having a field producing assembly (34, 34', 34a, 34b) providing a cup-shaped air gap (133) which is circumferentially disposed about an axis of rotation. The field assembly (34, 34', 34a, 34b) produces a circumferential distribution of magnetic flux in the cup-shaped air gap (133) having n periodic extremes of flux density (34, 34', 34a, 34b) about the axis. A cup-shaped electrical assembly (128) or armature is disposed in the air gap (133) and the armature (128) and field assembly (34, 34', 34a, 34b) are relatively rotatable. The armature (128) has a circular array of C non-overlapping coils (131) on each of its inner and outer faces with the coils (131) on one face being angularly offset from the coils (131) on the other face. Moreover, since the air gap (133) and coils (131) are cup-shaped, it is possible to achieve, for a machine of given diameter and form factor, a horsepower and torque which was previously possible only with substantially larger disk-type motors. That is because the total volume of the air gap (133) and coils (131) correspond to those of a much larger diameter disk-type motor.
