СИСТЕМА ЗАМЫКАНИЯ ПАЗОВ

Система для замыкания заполненных проводящими стержнями или катушками пазов тела статора из листовой стали электрической машины с помощью концевых замков-пазов содержит верхнее призматическое тело, на нижней стороне которого наклонно проходит поверхность, и нижнее призматическое тело. Обращенная к верхнему телу верхняя поверхность проходит наклонно относительно наклона нижней поверхности верхнего тела в противоположном направлении, причем непосредственное заклинивание осуществляется путем относительного взаимного смещения обоих призматических тел. Чтобы можно было оптимально использовать упругость верхнего тела в поперечном направлении, усилие от проводящего стержня или катушки передается на верхнее призматическое тело по всей длине в основном только на среднем участке. Тем самым в распоряжение предоставляются большие пружинящие усадки в радиальном направлении, которые в свою очередь могут компенсировать усадочные явления в конструкции обмотки. Таким образом увеличиваются интервалы технического обслуживания и повышаются возможности использования машины. 1 ил.

Slot closure wedges for stator cores

Apparatus includes pinch wheels that both advance wedge material stock and also substantially permanently form the stock material to precise dimensional tolerances by reducing the material thickness; means by which the formed material is retained in the formed configuration thereof; wedge severing means; and means for loading severed wedges into a wedge magazine. One of the pinch wheels is driven through a clutch-brake system arranged so that it may be driven unidirectionally only from a reciprocating drive arm. The wedges have precisely controlled dimensional tolerances and dimensional stability, with the result that the wedges lie squarely in stator core slots (when the wedges are inserted into such slots), and "wire over wedge" problems associated with skewed wedges in stator core slots are overcome.

NUTENTEIL EINES ELEKTROMOTORS UND VERFAHREN ZUR HERSTELLUNG DIESES TEILES

In an e.g. permanent magnet electric motor, slots (3) are stamped in the sheet steel laminations forming the stator or rotor iron circuit to accommodate the winding (10). The magnetic flux is channelled to the air-gap through the teeth (2) thus formed. Each tooth is notched (8) near the tip, on either side, to receive the ends of the bridge-pieces (4), themselves stamped from the same sheet as the main laminations, which close the slot mouth over the whole length of the stator or rotor core. The correct assembly of these laminations is aided by holes stamped near each end whose rough edges, on one side, tend to bed into the slightly chamfered hole on the other face of the adjoining lamination. Bridging greatly reduces the variation in flux as each permanent magnet pole passes over the teeth. Corresponding reductions in eddy current loss allow the motor current to be increased, more than offsetting the loss of torque due to slot enclosure. Similar arrangements are described for motors with ...

An assembly and a method for preventing an axial migration of a spring in a generator rotor are presented. The assembly includes a step pin radially disposed through an amortisseur and inserted into a spring of the generator rotor. The step pin is arranged axially apart from an adjacent radial vent passage and radially extends through the spring into a slot clearance between the spring and a creepage. The amortisseur includes a counter bore to retain a pin head and a pin shoulder. The spring includes a pin hole for a pin body extending therethrough. Diameters of the counter bore and the pin hole are smaller than diameters of amortisseur radial vent aperture and spring radial vent aperture. The step pin prevents an axial migration of the spring in rotor slots.

Flare tooth stator for an AC generator

A stator core extends along a longitudinal axis and includes a yoke, and a plurality of radially-inwardly projecting teeth separated by intervening slots. A radially innermost portion of each tooth initially includes a pair of legs separated by a recess disposed therebetween. The conventional tooth tips are unformed in the first stage, thereby defining an increased-size slot opening for allowing the insertion of stator windings. In a second processing stage, after the core itself has been manufactured and wound with stator windings, the legs are cold-formed in order to form tooth tips, which define a reduced-size slot opening to provide a magnetic flux path and provide a wire retention function. A higher stator slot fill is provided, which allows and enables higher generator efficiencies and output for a given package size.

Filler pieces (1) are arranged between the pole shoes so that they are connected together to form a closed bore that acts as a support for the plastic sleeve (3) between the stator and the rotor. The filler pieces are made of sheets of electrically insulating material. AN Independent claim is also included for a method of manufacturing an electric motor.

Slot closing assembly

The arrangement for closing the slots (which are filled with conductor rods (4) or coils) of the laminated stator core (5) of an electrical machine by means of slot closure pieces comprises an upper prismatic body (1) on whose underneath (8) a surface runs in an inclined manner, and a lower prismatic body (2). The upper surface (9), facing the upper body, runs in the opposite direction to the gradient of the lower surface (8) of the other body, the actual wedging being carried out by relative displacement of the two prismatic bodies (1,2) with respect to one another. In order to be able to utilise the elasticity of the upper body (1) in the transverse direction optimally, the force of the conductor rod (4) or coil on the upper prismatic body (1) over its entire length is introduced essentially only in its central section. In consequence, relatively large spring movements in the radial direction are available which, for their part, can better compensate for seating phenomena in winding construction ...

Coil injection methods and apparatus in motor manufacture

Abstract of the Disclosure An injection shuttle system is disclosed for fabricating stator core assemblies. Injection tooling and a stator core are selected and positioned on a shuttle means at a selection station for moving to coil loading stations and a transfer station. The injection tooling is positioned, aligned and manipulated relative to a winding machine at each coil loading station for disposing winding turns thereon. At the transfer station, the injection tooling is transferred to a wedge guide housing of a turntable arrangement which includes wedge making and injection stations. A stator height adjustment arrangement is provided for adjusting the wedge making and injection stations in accordance with the axial length of the core. The injection tooling is moved or indexed to the wedge making stations where insulating wedges are fabricated and inserted into wedge guides of the wedge guide housing. The injection tooling is then moved to the injection station where the core is interfitted with the tooling by a core transfer assembly. An injection mechanism at the injection station then injects or transfers the winding turns and insulating wedges into axially extending slots of the core. The end turns of the windings are then moved away from the bore of the core by an end turn separator. The injection tooling with winding turns removed therefrom is indexed or moved to an unloading station where it is transferred from the turntable arrangement to a shuttle means for subsequent transfer back to the selection station.
