摘要： A number of embodiments of rotating electrical machines and methods for winding them that provides a high space utilization and very effective winding with less likelihood of damage to the insulation of the wire of the winding during the winding process. The arrangement basically does not require the winding needle to be moved back and forth in the slot between the poles but rather employs insulating inserts that are positioned on the axial faces of the poles outside of the gaps for guiding the wire from one end to the other so as to provide the high space utilization. In one embodiment the insulating insert effectively changes the circumferential length of the coil winding that decreases in an axial direction along their length.

摘要： Rotary permanent magnet motors have salient stator poles with nonuniform pole thickness in the radial direction for compensating effects of cogging torque. Pole base portions terminate at pole shoes at the radial air gap. The pole shoes extend in the circumferential direction from the bulkier base portions. Variation of the thickness of the pole shoe changes the concentration of the effective flux at the point of coupling between the stator poles and the permanent magnet pole shoes. As there is no change in the active interfacing area of the pole shoes a uniform air gap is maintained. The torque signature for each stator pole/rotor permanent magnet interface can be selectively changed to smooth motor operation by configuring the stator pole shoe thickness to vary along its circumferential extent as appropriate. Pole shoes may have tapered leading or trailing edges with respect to a pole base to change the effective flux density in the air gap at a specific pitch of rotation. Additionally, the pole shoe may be shifted off center with respect to the pole base.

摘要： The micromotor serves to drive an impeller (12) rotating in a pump housing (14). The excitation winding of the micromotor is surrounded by an enveloping flux return structure (18) of ferromagnetic material divided into rings (35). The rings (35) are separated from each other by slots (25). The slots are produced by laser cutting of a continuous tube. The enveloping flux return structure has a small wall thickness of a few tenths of a millimeter. The rings (35) are mutually connected by bridges (26). The enveloping flux return structure (18) can be integrally formed with the pump housing (14) of the pump (11). The micromotor can be produced in a small format with a small diameter. It has a high flow rate at a correspondingly high rotational speed. The micromotor is particularly suitable for introducing blood pumps into the vascular system in a non-operative minimally invasive percutaneous manner.

摘要： The invention concerns a generator for a windmill. The generator is of the kind being directly coupled to the main shaft of the wind rotor of the windmill. The generator is a stator consisting of a number of stator modules that are individual and which may be installed, repaired and dismantled individually and independently of each other. This implies that it is very easy and thereby cheaper to mount the mill, especially at sea, as the stator for the generator can be transported in smaller units, which also makes it easier to assemble the stator in the tower top section. By sequent repairs and other maintenance of the generator it is not necessary either to use large cranes, but it is sufficient to use smaller hoisting devices that may be handled by one or two persons.

摘要： A motor assembly having improved flux density includes a field assembly and an armature assembly rotatably received by the field assembly. The field assembly includes a plurality of like laminations stacked upon each other wherein each field lamination comprises a pair of substantially parallel bracket sides, and a pair of substantially parallel yoke sides which are substantially perpendicular to the pair of bracket sides. Corner pieces connect the yoke sides to the bracket sides wherein the corner pieces are angularly directed between about 40° to about 50° with respect to the yoke sides and the bracket sides. A yoke extends inwardly from each yoke side to form an armature opening therebetween for rotatably receiving the armature assembly. The bracket sides, the yoke sides and the corner pieces forming airflow areas therein, and the bracket sides, the yoke sides, (except at the yokes) and the corners all have substantially the same width dimension, such that the yoke sides, the bracket sides and the corners have substantially equivalent average field flux density ratios.

摘要： An electromagnetic motor has an outer housing and a shaft rotatably mounted in the housing to extend along the central axis and out through one end of the housing. A plurality of electromagnets are mounted in the housing at spaced intervals around an annular ring centered on the central axis. An elongate rotor member of ferromagnetic material is secured to the shaft and projects in diametrically opposite directions radially outwardly from the shaft up to the annular ring of electromagnets. A power supply is connected to successive diametrically opposed pairs of electromagnets through a switching assembly such that the ends of the rotor are attracted to successive activated melectromagnets in the ring, thereby rotating the shaft.

The electromagnetic assemblies define a plurality of stator poles.

A switching arrangement for controlling the electromagnetic assemblies is configured such that the switching arrangement is able to cause the stator poles of the electromagnetic assemblies to magnetically interact with the rotor poles of the rotor arrangement within a certain range of frequencies. The number of rotor poles is selected to be a number such that the switching arrangement causes the stator poles of the electromagnetic assemblies to magnetically interact with the rotor poles of the rotor arrangement in a way which causes the ratio of the frequency of the device in cycles per second relative to the revolutions per minute of the device to be greater than 1 to 4 during the operation of the device.
