Abstract

The invention relates to electrical engineering, in particular to an electrical machine which has induction saturation of a magnet core, fed with three-phase current and provided with a combination winding. One part of said winding is connected in a star and the other part is connected in delta, a spatial offset between said parts not being equal to πm/3p, where m is a whole number. The invention is characterised in that a shortening or elongation of a coil pitch β within a value range 0.5 n<β< (0.5n=0.5), where n=1,2, (shortening or elongation equal to β=2/3+2/3k, where k=0,1, is most efficient), and/or a winding angle distribution (most efficient phase distribution is at the angle α = 2π/3p+2kπ/3p, where p is number of pole pairs). The invention reduces a current load of the triangle and dependence on the voltage of a ratio between star currents and delta currents.

Signs of the analogue:

1. Combined access;

2. The parallel connection of the star and the tragus; 3. Nourishment with a tripe;

4. The ratio of the number of turns in the phases of the star and the receiver, which ensures the required share of the downloads.

The first and third terms coincide with the essential attributes of the claimed invention. A short way is to achieve a result that is only at a single voltage value. Any change in the supply voltage may result in the separation of the parts being handled.

The closest analogue is the “Installing the machine and / or the processor and engine with improved temperature [47]” Signs of the analogue: 1. Combined processing; 2. Pigging with a random phase;

3. Mutual displacement of the star and the satellite in an angle of π / 2ρ ± π / бρ, where ρ is the number of polar pluses.

The first and second terms of the analogue are the same as those of the claimed invention. The disadvantage of the closest analogue is that there is an increase in the consumption of the industrial product and an increase in the electrical process due to the reduction of the cost of the product.

ΡΑСΚΡЫΤИΕ ΕΟΟΡΕΤΕΗΡΕΤΕΗ

The invention is supplied to electric machines by all the below listed products: - the combined product is free of charge; food supply; A simple mutual shift of the parts of the sample is not equal to πιηΙЬρ, where m is an integer; saturation of the steel magnet. 3 Pοlοzhigelny eφφeκτ οτ izοbρeτeniya sοsτοiτ in reducing zagρuzκi τοκami οbmοτκi τρeuτοl- niκa and τaκzhe umenyπeniya zavisimοsτi οτnοsheniya τοκοv τρeugοlniκa κ τοκam stars οτ πiτayuschegο naπρyazheniya in ρezulτaτe isποlzοvaniya uκοροcheniya or elongation and / or ρasπρedeleniya κοmbiniρο- vannοy οbmοτκi eτiχ eleκτρichesκiχ machines πο sρavneniyu with eleκτρichesκimi machines not having an amendment or extension or / and separation or having a worse value of these parameters.

The use of the invention, in addition to an increase of 2/3, gives the same effect of decreasing the load of the test and reducing the dependence of the increase of the speed of the voltage However, there is a significant margin of safety for this, as it reduces the length of the front end by one third (the length of the forehead must be removed).

When sharing the unit, install the unit in phases, and at the same time, connect and disconnect the unit (often connected)

We take into account the case when the non-sinusoidality of the mag- netic power supply circuit breaks down due to the fact that there is a reason for the saturation of the magnet to become unlimited. The flow generated by the combined trade is the imposition of the proceeds generated by the processing of the goods and the arrivals of the goods, the incidental Having paid the fastest changes in time and spare parts for garmonical components, we will make the equalities for the short-term industrial goods:

Φ is the maximum value of the μ-temporal part of the phase flow process, divided in the part of the part of the ν-grammar; μ is the number of the regular garage; ν - a number of a regular garage; I - variable time; Τ- in advance of a change in the course of time; χ - variable variance; 4 τ - in the event of a change in the flow in the facility;

2. For starters

Φ is the maximum value of the μ-temporal variance of the phase of the star, which is distributed in the constituent of the ν-variance; γ is the angle of the spatial shift of the sample of the star of the relative sample of the cart,

In each of the available industrial time models with numbers μ = bα and ν ≠ bά, where α and ά are natural numbers, they are equal to zero. Indeed, for both α and ά ав ά нения нения ненияав ав ав ав ав ав ав ав ав ав ав ав ав ав ав ав ав ав ав ав ав нения нения ав ав α α α α α α α α α ин, in addition to the fact that there is a slight difference between the two components, the absolute value of the two components is relatively constant. Α the sum of such cosines is equal to zero.

In general, for any spare part of the temporary component of the product, the presence of a large volume of the product At the same time, all spare parts of the secondary part of the process are pulsating.

As a rule, a larger amplitude among the temporary garments of the electric machine is a lot of goods with smaller ordinary ones, that is, they are free of charge. Therefore, for further quantitative analysis, it is possible to neglect the presence in the mag- netic source of electrical equipment of the remaining temporal garments.

We have a direct access to the system, a star connected to it. Let us assume that by acting on a three-phase sinusoidal voltage in phase-by-phase transient, it is a sinusoidal voltage. The initial value of the first harmonic of the flow is equal to 1Φ, the third harmonic of the flow is 0, 1Φ.

Let us see the magnetic flow of the machine, the negative diametrical winds of Sh, VI, and the quick-contact are compatible with the phase of the process of generating the magnetic magnets. In the drawing (see, Fig. 2), the use of the magnetic circuit for the turn of the Sh and its decomposition to the first and second garments is shown. The inlet flow and its components in the other arcs VI, Ψ1, shifted by ± 2π / 3 in time, have a temporary shift of ± μ2π / 3.

Since the flow of the garbage is pulsating and the angle δ is for 5 wrought-iron ports νπ / 6 = π / 2, which means 1) 2, VI, Ψ2 are not connected to the flow of the garbage. In general, with the W, VI, Ψ2 branches, there is a connection only to the first garbage warehouse. In the picture (Fig. 3), the use of a magnetic feed for the Sh. In this case, the constituent flow, which is connected with the turnkeys, and the complete process flow is created by the same day and the same. Α this means. part of the process flow associated with the W, U2,

Ψ2 The instantaneous value of the induction cannot be greater than the instantaneous value of the induction of a complete trial. Consequently, the maximum value of the component that is connected with the 112, ν2, Ψ2, or the amplitude of the first case is, in fact, very important. Correspondingly, the amplitude of the Front End of the Front in the Shorts, VI, C2 is 0,9Φ. Β At the same time, the amplitude of the front part of the garbage for the W, V, Ψ1 branches is 1Φ and the amplitude of the front part of the gate is in the Vitac

This is explained by the fact that, in the case of a sample of the regulator, in contrast to the star, there are short-circuiting temporary components, which reduce the volume of the armature. In general, the process of handling the cassette contains a significantly reduced time-consuming garbage. For further quantitative analysis, it is possible to neglect the presence of a temporary temporary garbage in the factory.

Combined storage in the room:

The number of openings for the pole and the phase in the field of the path and star is the same unit; Phases of a star consist of diam eter rotations shifted in space between themselves by a 2π / 3 angle; Phases of the partition are made up of diam eters, shifted in the space between the angle of 2π / 3; Shift of the sample of the star in the case of the π / 6

In the second case (see Fet. 1), the processor will be removed from the main circuit, as well as in the case of a vehicle. In contrast to the star (due to the presence of a circuit for closure), there is a short circuit in the main components of the circuit. Α All non-compact ones have a harmonious ratio of the amplitude in the star to the amplitude in the case equal to 1,732, a shared circuit connection.

In general, there is a reason for the presence of large-scale electrical and magnetic components, a wiring or an external wiring, For its reduction, it is sufficient to reduce the private time-frames of the second-hand flow. As a matter of fact, it is noteworthy that, at the same time, the spare time part of the manual process may be present in the vehicle part of the vehicle. In order to make it easier to reduce the regular-time harmonic, to sufficiently reduce it only in the device. All the other spare garmonic parts disappear when you shorten (lengthen) the step of the scan β = 2/3 + 2 / bk. The simpler wider garment has a smaller acceleration factor than the first simpler variation (lengthening) of a step of 0.5 + 0.5 times. All the other parts that are partly part of the normal family disappear and the whole 7 of the division of trade, for example, and the phase angle α = 2π / bp + bp / bp.

By decreasing the three-phase voltage flow, a lower dependence on the output voltage of the starter current circuits is achieved. Actually, in the event of a change in the supply of food, the main flow changes, therefore, the saturation of the magnetic flux and the waste of the pressure is changed. That happens (see, for all) to the separation of the path of the star and the angle of the star and the change in the ratio of the star to the star. Decreasing the short circuit, the harmonious process by reducing or extending or / and separating we, when changing the voltage, we make a smaller change in the diminished variable, and they increase the value.
