Description
Technical field
The utility model is related to a kind of motor, particularly a kind of rotor structure of permagnetic synchronous motor.
Background technology
Permagnetic synchronous motor has the excellent properties of energy-conservation relative to cage induction motor, is the item that state key is promoted
Mesh.Because permanent magnet need to be embedded in the rotor of squirrel-cage motor the silicon steel die, it is necessary to new, die cost is high, however, permanent magnetism
Synchronous motor is in the popularization stage, generally separate unit or a small amount of demands, causes expensive, and influence is promoted.
The content of the invention
The purpose of this utility model is to provide a kind of suitable single-piece and small lot production and improves the positive performance of permanent magnet magnetic
A kind of permagnetic synchronous motor rotor structure.
The technical solution of the utility model is, a kind of rotor structure of permagnetic synchronous motor, including squirrel-cage bar, rotor and forever
Magnet, it is characterised in that：The strip permanent magnet with motor pole number identical radial direction is uniformly distributed with along the circumference on rotor, in rotor
Bottom has been evenly distributed and the strip permanent magnet number identical arc-shaped permanent magnet, above-mentioned strip permanent magnet and arc-shaped permanent magnet
The rotor is divided into motor pole number identical sector shaped magnetic area, two strip permanent magnet phases in any one sector shaped magnetic area
To surface polarity and the polarity all same on arc-shaped permanent magnet outer arcuate surface, the magnetic in sector shaped magnetic area is by constituting the fan
The polarity of the strip permanent magnet apparent surface of shape magnetic area two and the polarity decision in arc-shaped permanent magnet outer arcuate face, adjacent sector
The magnetic of magnetic area is differed, and the external end head of the strip permanent magnet is outside the strip shape gob in outer diameter small cone and rotor
The conical opening of termination matches.Axially extending bore is set on the external rotor of the arcuate permanent magnetic, rotor is cooled.
The utility model has the advantages that the low and suitable single-piece of price or small lot production compared with the prior art.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The technical solution of the utility model on rotor as shown in figure 1, be evenly distributed and motor series（Such as quadrupole）
Identical radial direction strip permanent magnet 1, is evenly equipped with and strip permanent magnet number identical arc on the rotor 3 of motor axis hole 5
Rotor is divided into four sector shaped magnetic areas, institute by permanent magnet 4, the strip permanent magnet of aforementioned four radial direction and four arc-shaped permanent magnets
Stating the two sides of strip permanent magnet has different polarity（N、S）, the inside and outside arcwall face of the arc-shaped permanent magnet has different
Polarity（N、S）, constituting the magnetic requirements in sector shaped magnetic area is, the magnetic on the relative surface of two adjacent radial direction strip permanent magnets
With the magnetic all same of the outer surface of arc-shaped permanent magnet, such as N poles, the magnetic area is N poles magnetic area, it is desirable to adjacent magnetic area
Magnetic it is far from it.In order to improve the performance of permanent magnet, four outer faces of strip permanent magnet for being radially arranged and rotor
Outer peripheral face maintains an equal level, and the external end head of strip permanent magnet is provided with into the small cone of an outer diameter and the taper of rotor strip shape gob termination
Mouth matches, and the effect one of this cone structure is enhancing permanent magnet performance, and two be to prevent that permanent magnet is thrown out of when motor from rotating.It is described
Each strip permanent magnet, which should try one's best, reduces destruction to squirrel-cage bar 2, and axially extending bore 6, work are set on the external rotor of each arcuate permanent magnetic
It is beneficial to cool to rotor when making.
Strip permanent magnet axially can be interted into arc-shaped permanent magnet by spliced together by right-hand member, and and glue
Stick filling bonding, prevents surrounding from loosening, and is axially divided into fritter strip permanent magnet outer end cone and cone mouth and matches, during processing by
Periphery point quadrupole radial direction milling deep trouth, the milling cone body mouthful again in groove（Two end ring are not destroyed）, fritter strip permanent magnet is by the axial right side
Left end is shifted in the expansion mouthful insertion at end, and with secondary operation adhesive bonding, last block fritter strip permanent magnet, circumferential Shu Gu is without latitude
Band, prevents from throwing away.
Above-mentioned permanent-magnetic synchronous motor rotor structure, wire cutting and machinery are passed through using identical cage induction motor rotor
Cutting Process transformation is formed, and without designing and manufacturing mould, thus price is low, with short production cycle, is suitable for single-piece or small
Batch production, is conducive to popularization and application.
