Stator design for low-power three-phase asynchronous motor Stator design for low-power three-phase asynchronous motor / 2505909
Stator is a salient-pole stator but its salient poles do not have windings and a tooth area. The three-phase winding of the stator, which generates a system of phase magnetomotive forces (mmf), is lumped in form of coils and is placed on radial protrusions (poles) of a frontal core placed on one of the ends of the stator perpendicular to the axis of the asynchronous motor with a central opening for the shaft. The poles of the frontal core with windings are magnetically closed with the stator poles by steel rod bundles. The novelty in the design of the stator is that elements of its magnetic conductor along with the rotor core form a symmetrical multi-phase magnetic circuit connected by a Y connection with two node "points": in the frontal core of the stator and in the rotor. Under the action of the symmetrical system of mmf, a phase magnetic flux system which is symmetrical in space and time (on phase) arises in phases of such a symmetrical magnetic circuit. Summation thereof gives rise to a circular revolving magnetic field of the stator, and node "points" of the magnetic circuit have zero magnetic potential, owing to which the phase magnetic flux of the stator crosses the air gap only once in the forward direction: stator pole - air gap - rotor core, and have only the normal (radial) component of the magnetic induction vector. Return flux and tangential components of the induction vector are absent in the back of the rotor.

The invention relates to a low-speed contactless torque of the electric machines with permanent magnets and can be used to convert the energy of rotation of the rotors of small wind and hydro power plants into electric current with compensation of the magnetic force holding the rotor evenly loaded output winding.

Known electric machine with the disk rotor by the patent RU №2340068 from 27.11.2008, [1], containing nonmagnetic case of two halves with bearing units for the rotor shaft, the magnetic circuit and the windings of the stator, the rotor disc type, placed on a ring magnetic sectors with mutually opposite magnetization vectors along the short axis and passing during the rotation of the rotor in the air gap of the O-shaped electromagnetic systems (EMS) of the stator.

O-rings EMC stator consist of two U-shaped parts with the windings of the stator, placed in the halves of the body. When a magnetic sectors of the rotor in the air gap of the stator EMC in its magnetic core varies the magnetic flux that causes the EMF on the conclusions of the stator windings. To reduce the influence of the magnetic force holding sectors of the rotor in the stator clearances EMC prototype [1] used the known method and device of reciprocal compensation braking force into electricity is th generator with permanent magnets according to the patent RU No. 2394336 from 10.07.2010, [2], in which the magnetic circuits of the stator EMC performed with a constant magnetization of the poles, and the strength of the magnetic pull in air gaps of one stator EMC balanced magnetic forces pushing sectors of the rotor disk of the air gaps of the other stator EMC.

Significant disadvantages of the prototype [1] are:

- high consumption of materials design and technology complexity ensure free rotation of the rotor in the air gap of the stator EMC O-shaped type because of the high magnetic force of attraction of the magnetized sectors of the rotor to the stator poles EMC;

- unproductive losses due to the increased magnetic resistance of the stator EMC because of the considerable length of the average magnetic line and a significant air gap O-shaped core.

The technical result achieved by using the proposed invention is to reduce material consumption and improve maintainability and energy efficiency of the design.

To achieve a technical result stator EMC electric machine is made U-shaped with open poles facing the open poles of the magnetic elements of the rotor are connected in pairs by means of magnetic jumpers placed on the opposite side of the rotor relative to the open floor is cos its magnetic elements, the distance between the centers of the poles of the stator EMC is equal to the distance between the centers of adjacent poles of the magnetic elements of the rotor.

1 shows a disk rotor of the electric machine /top view and side view in section of/; figure 2 shows the relative positions of the rotor disk and one of the stator EMC /top cut from an end face of the rotor at the bottom of the top/when the magnetic flux from the permanent magnets of the stator EMC is summed with the magnetic flux from the permanent magnets of the rotor; figure 3 shows a variant of vzaimovliianie magnetic fluxes from the permanent magnets of the stator EMC and rotor, and Fig 4 shows an intermediate position of the poles of the stator EMC relative to the poles of the magnetic rotor systems, in which the magnetic resistance of the stator EMC maximum because of the significant air gap in the magnetic circuits of the stator EMC; figure 5. shows an intermediate position of the poles of the stator EMC relative to the poles of the magnetic rotor systems with an alternative placement of the magnetic elements of the rotor.

The non-magnetic disc 1 of the rotor is fixed with a constant angular pitch of the magnetic sectors 2, pairs United magnetic jumper 3 in the U-shaped permanent magnet facing the open poles to open poles of the U-shaped stator EMC containing ferromagnetic elements 4, 5, 6 and the stator is bmode 7, posted on frame 8

When the rotation of the disk 1 of the rotor relative positions facing to each other of the open magnetic poles of the elements 2 and rotor 4, 5 of the stator passes several characteristic phases:

- phase maximum of the resulting magnetic flux in the stator EMC shown in figure 2, when in the air gaps between the poles interact with the opposite poles of the elements 2 and 4, 5, resulting in a cumulative magnetic stator EMC and the corresponding rotary magnetic system;

- minimum phase magnetic flux in the stator EMC, is shown in figure 3, when the air gaps between the poles interact with the same poles of the elements 2 and 4, 5, resulting in vzaimokompensiruyutsya magnetic stator EMC and the corresponding rotary magnetic system;

- phase intermediate values of the magnetic flux in the stator EMC, depicted in figure 4, when the size of the air gaps between the magnetic poles 2 and 4, 5 maximum, also maksimalno magnetic resistance of the respective stator EMC.

In all other mutual locations of the elements 2 and rotor 4, 5 stator EMC is changing the values of the flows between these two phases, creating in the output windings 7 EMF is proportional to the number of turns of the winding and the rate of change of magnetic flux. When che is nom the number of pairs of stator EMC in the proposed device is provided for effective compensation of the magnetic force of retracting the rotor of one pair of stator EMC forces of magnetic repulsion of the rotor from similar provisions other a pair of stator EMC. As a result, when unloaded /or uniformly loaded/ output windings of the stator EMC easily rotor rotates against the backdrop of a significant vzaimokompensiruyuschim each other forces the magnetic interaction of the magnetic poles of the rotor with magnetic poles of the stator EMC.

Figure 4 shows a variant of the placement of the poles of one of the pairs of stator EMC /left in figure 4 stator EMC/ and other pairs of stator EMC /right on the 4 stator EMC/ around the circumference of the rotation of the magnetic sectors of the rotor with alternating polarity open poles. At the same time, the variant shown in figure 5 pairwise accommodation in the rotor of the two sectors of the same magnetization, in which the orientation of the poles of all the stator EMC circumference of rotation of the magnetic sectors of the rotor will be the same, however, would be provided for effective compensation of the magnetic force holding the rotor

Compared with the prototype in the proposed device:

- reduced consumption of materials design /used a smaller number of magnetic elements in the stator EMC/;

- simplified technology of Assembly and disassembly design, due to the unilateral placement of the disk rotor relative to the stator poles EMC;

- by placing the poles of the stator EMC in the same plane provided the opportunity to both reduce air for the ora between the poles of the rotor and stator, and the average length of the magnetic line of stator EMC, which significantly increases the efficiency of the device.
