摘要： A direct current brushless motor includes a base having a receiving chamber whose one end is combined with a cover plate. The other end of the receiving chamber and the cover plate each have a shaft hole, for pivoting the rotation shaft of the rotor. A film printed circuit is mounted on the periphery of the base. The film printed circuit has at least two coil sets, a set of Hall sensing drive member, and a connecting end for connection with a power supply. The coil sets are oppositely distributed on the periphery of the base in an equally angular manner with the receiving chamber serving as a center. After the coil sets are energized, the multiple coil sets and the permanent magnet ring of the rotor may produce mutually repulsive forces, so that the rotor may be driven to rotate successively.

摘要： A winding support structure for use with a superconducting rotor and method for forming the same comprises an inner support ring, an outer support ring arranged around the inner support ring, first and second support blocks coupled to the outer support ring and a lamination coupled to the first and second support blocks. A slot is defined between the support blocks and between the outer support ring and the lamination to receive a portion of a winding. The inner ring is a solid ring and the outer ring is a split ring. The outer ring expands to produce a radially outward force against the support blocks and the winding when the inner ring is moved axially with respect to the outer ring. An RTV fills any clearance space in the slot.

摘要： A rotary electrical machine (1) has at least one stator (23). The stator is provided with at least one radial channel (107) for ducting cooling air. The channel (107) extends between a first position (113) at or substantially near the rim (109) of a winding region of the stator (23) and a second position (119) at or substantially near the center (51) of the winding region. The machine (1) has cooling means (91-97) for causing cooling air to enter the radial channel (107) via the second position (119) and exit via the first position (113). The stator may have electrical windings arranged as coil sectors (183-197) disposed substantially equi-angularly in a generally circular pattern. At least some of the coil sectors are wound in a generally spiral fashion when viewed axially. A rotor (13), for the machine may have a plurality of equi-angularly spaced magnets (127), which are generally circular but with a cut-away portion, when viewed axially.

摘要： A method of securing a stator winding such that it has improved heat dissipation performance includes steps of inserting a stator winding into a stator core soaking these components in a varnish tank while being held together as one, and after the varnish has soaked into the stator winding 15, withdrawing the winding and core from the varnish tank. Then a mandrel comprising an outer peripheral pressing portion made by wrapping a fluororubber around an outer periphery of a mandrel body made of a fluoroplastic, is inserted into the stator winding. After this, the varnish is heat hardened with the stator core, the stator winding, and the mandrel 33 all held together as one. In so doing, the outer peripheral pressing portion is deformed with irregularities replicating the inner periphery of the stator winding 15. Hence on the inner peripheral side of the stator winding, the varnish resin hardens with the irregularities retained. As a result, the effective inner peripheral surface area of the stator winding with the hardered varnish is increased, and heat dissipation is thus improved.
摘要翻译：一种固定定子绕组的方法，使得其具有改善的散热性能包括将定子绕组插入定子芯中的步骤，将这些部件浸入清漆罐中，同时保持在一起，并且在清漆浸入定子绕组中之后 15，从清漆罐中取出绕组和芯。然后，将包括由氟塑料制成的心轴的外周围的氟橡胶制成的外周加压部的芯棒插入定子绕组中。此后，清漆与定子芯，定子绕组和心轴33全部热固化在一起。这样做时，外周按压部分会使定子绕组15的内周上的凹凸变形。因此，在定子绕组的内周侧，清漆树脂硬化，并且保持不规则。结果，增加了具有硬化清漆的定子绕组的有效内周面积，从而提高了散热。

摘要： Some of linear motors which constitute an exposure apparatus have coils each obtained by winding a copper foil wire as a foil-like conductor having an insulating layer around a core member in a multilayered structure. The coil is fixed to a positioning portion serving as the coil fixing portion of the linear motor by using the core member. The core member is formed from the same insulating material with low thermal conductivity as that of the positioning portion of a linear motor housing or a material with almost the same linear expansion coefficient.

摘要： An electromechanical machine is disclosed which has a field producing assembly providing a cup-shaped air gap which is circumferentially disposed about an axis of rotation. The field assembly produces a circumferential distribution of magnetic flux in the cup-shaped air gap having n periodic extremes of flux density about the axis. A cup-shaped electrical assembly or armature is disposed in the air gap and the armature and field assembly are relatively rotatable. The armature has a circular array of C non-overlapping coils on each of its inner and outer faces with the coils on one face being angularly offset from the coils on the other face. Moreover, since the air gap and coils 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 and coils correspond to those of a much larger diameter disk-type motor.
