DE19726424A1 - Level multiple circuit with compensation for permanent magnet internal pole generator - Google Patents

Abstract

The circuit includes e.g. a dual winding (W1,W2) on a stator. The number of primary magnets is an integer multiple of two, and the stator dual windings agree in number and angle with the rotor. The upper windings (W1,W2) of two sequential winding stators are connected in parallel, individually compensated by capacitors (C1,C3). The corresponding lower windings (W2,W4) are compensated by the intermediate capacitor (C2). Each circuit is connected to the next in series, or parallel.

Description

The invention relates to a multiple level circuit with Kompen sation as a voltage source circuit for permanent magnetic Inner pole generators according to claims 1 and 2.

A prerequisite for this stator circuit is a minimum two-part magnetic yoke in the effective magnet height (Mh), and in connection with an equipolar main magnet sequence (M _H1 ...), Opposite-pole intermediate magnets (M _Z1 ...).

The object of the invention consists in the best possible ductive implementation of an experimentally unequal multiplicity lig proven permanent magnetic field, in connection with a Source compensation.

The commercial benefit results from the possible one set of air coils, the elimination of iron losses and one almost non-reactive torque.

The problem is solved according to claims 1 and 2.

The advantages of the invention lie in the use of air coils in the absence of cooling, using a main magnet sequence with the same polarity (M _H1 ...) In halving the speed, and due to the almost non-reactive torque by field separation and separate induction by means of a dual winding Efficiency optimization due to reduced power supply.

The invention is described below with reference to the attached drawings Fig. 1, 2 and 3.

Show it:

Figure 1 shows a minimal two-part magnetic yoke, which additionally allows an inner and outer pole induction.

Figure 2 shows a square dual winding (W1, W2) in level reference to the freely chosen main magnet (M _H1 ) from an external view.

Fig. 3 shows the inventive level multiple circuit with compensation.

Fig. 1 shows a freely selected section from a conceived th, cast pot shape of the permanent magnetic rotor. The potting compound and the central axis, vertically arranged in terms of figures, have been omitted due to their expediency.

The permanent magnets used are magnetized regardless of their mate rial in the magnet thickness. The larger main magnets (M _H1 , M _H2 ...) Of the rotor have a magnet sequence which is preferably of the same polarity. The necessary intermediate magnets (M _Z1... ) Are arranged with opposite polarity. The upper magnetic return ring (K1) and the lower magnetic return ring (K2) are short-circuited to all magnets arranged over the rotor circumference.

Both return rings are made of soft iron or transformer sheet and can be interrupted up to four times over the circumference.

Fig. 2 shows a freely selected dual winding (W1, W2) on the winding stand (St1) fixed, in axial alignment with the effective magnet height (Mh) of the main magnet (M _H1 ). The dual windings (W1, W2) are connected to the following dual windings (W3, W4), not shown here, to form a wiring and power unit.

The number of main magnets (M _H1 ...) Is an even multiple of 2 and the stator dual windings (W1, W2). . . agree with 1-phase alternating current, numerically and angularly with the rotor.

In the three-phase version, the dual windings (W.., W..) Of the strands L ₁ , L ₂ , and L _{3 are} each 120 ° degrees of rotation apart on one magnetic plane of the rotor, or the necessary 120 ° offset is on three different magnetic planes of the Runner distributed.

The power supplied from the outside for the evenly accelerated inclined axis rotation in a defined direction of rotation, generates touch a sinusoidal course of an alternating voltage voltage in all generator windings (W...).

Fig. 3 shows the inventive level multiple switching with compensation and this is aligned for a better overview, here vertically aligned analogous to FIG. 2.

The practical implementation of experimental results that a magnetic field can be used to achieve a field division and one unequal but more advantageous current filing optimal with ana has to correspond to the H-values, has shown a circuit, which furthermore the different magnetic level, here between between top (o) and bottom (u), with different circuits each corresponding magnetic level.

The upper windings (W1, W3) of two successive The winding stands (St1, St2) are with the capacitors (C1, C3) individually compensated connected in parallel. The associated The lower windings (W2, W4) are centered with the condensate sator (C2) compensated connected in series. Both single scarves The following are either in series with one another or as shown connected in parallel and thus result in a power depending on the performance requirements in one way or another Limit circuit can be repeated several times.

With the power units described in each case adapted by means of a, analogous to the magnetic number (M _H1 ...) Of the runner adapted speed, non-contact inductive an alternating or rotary voltage with a fixed Hz number and sinusoidal curve is provided, which is immediately removable and commercial is usable.
