Abstract
The invention discloses a permanent magnet motor winding, which comprises a rotor and a plurality of permanent magnets, wherein the permanent magnet is elongated; the permanent magnets are arranged on the periphery of the side end part of the rotor to form an equilateral polygon; gaps are formed between every two adjacent permanent magnets; and the plurality of permanent magnets have the same width. In the permanent magnet motor winding, air-gap magnetic flux density Bdeltamax which is distributed according to a sine wave law at the center line of a magnetic pole still can be considered to be equal to magnetic flux density Bd at the center of magnetic steel, namely Bd is approximately equal to Bdeltamax. By the scheme, the utilization rate of the permanent magnet is greatly increased; and the scheme has a simple structure, and is practical.
Description
Technical field
The present invention relates to a kind of magneto winding, the air-gap field in especially a kind of permanent magnet utilance height and the gap belongs to the motor component technical field by the magneto winding that sinusoidal wave rule distributes.
Background technology
The field structure of existing magneto winding is varied, and pluses and minuses are respectively arranged. for example:
1, Surface Mount structure, permanent magnetic material need in addition in addition colligation to fix, and colligation material and adhesive curing process are complicated, and what have need magnetize on the frock that magnetizes specially with magnet charger after bonding, colligation, curing again;
2, mosaic texture has vertical and horizontal branch, and leakage field has reduced the utilance of permanent magnetic material usually more than 15%;
3, permanent magnetic material has the uniform thickness and the branch of uniform thickness not, and uniform thickness material processing technique property is not poor, and permanent magnetic material utilizes rate variance.
Summary of the invention
The present invention seeks to have proposed the magneto winding that the air-gap field in the high and gap of a kind of permanent magnet utilance distributes by sinusoidal wave rule for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of magneto winding comprises rotor, permanent magnet; Said permanent magnet becomes strip; Said permanent magnet has a plurality of, and just changeable shape is arranged on the periphery of the side end of rotor; Be provided with the gap between the adjacent permanent magnet; The thickness of said a plurality of permanent magnets is all identical.
Preferably, the minimum place in said gap is greater than 2 millimeters.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Magneto winding of the present invention at pole center line place, still can be considered equal by the air gap flux density B δ max of sinusoidal wave rule distribution and the close Bd of magnetic of magnet steel center, i.e. Bd ≈ B δ max; This programme has improved the utilance of permanent magnet greatly; The present invention program is simple in structure, practical.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the sketch map of magneto winding of the present invention;
Wherein: 1, rotor; 2, permanent magnet; 3, gap.
Embodiment
Be depicted as a kind of magneto winding of the present invention like accompanying drawing 1, comprise rotor 1, permanent magnet 2; 2 one-tenth strips of said permanent magnet; Said permanent magnet 2 has a plurality of, and just changeable shape is arranged on the periphery of the side end of rotor 1; Be provided with gap 3 between the adjacent permanent magnet 2; The thickness of said a plurality of permanent magnet 2 is all identical; The minimum place in said gap 3 is greater than 2 millimeters.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Magneto winding of the present invention at pole center line place, still can be considered equal by the air gap flux density B δ max of sinusoidal wave rule distribution and the close Bd of magnetic of magnet steel center, i.e. Bd ≈ B δ max; This programme has improved the utilance of permanent magnet greatly; The present invention program is simple in structure, practical.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
