Description
Technical field
The present invention relates 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, it is necessary to new silicon steel die, die cost is high, however, permanent magnetism
Synchronous motor is in the popularization stage, generally separate unit or a small amount of demand, causes expensive, and influence is promoted.
The content of the invention
It is an object of the invention to provide a kind of suitable single-piece and small lot batch manufacture and improve the positive performance of permanent magnet magnetic it is a kind of forever
The rotor structure of magnetic-synchro motor.
The technical scheme is that, a kind of rotor structure of permagnetic synchronous motor, including squirrel-cage bar, rotor and permanent magnetism
Body, 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, under rotor
Portion has been evenly distributed incites somebody to action with the strip permanent magnet number identical arc-shaped permanent magnet, above-mentioned strip permanent magnet and arc-shaped permanent magnet
The rotor be divided into motor pole number identical sector shaped magnetic area, two strip permanent magnets are relative in any one sector shaped magnetic area
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 sector
The polarity decision of the polarity and arc-shaped permanent magnet outer arcuate face of the strip permanent magnet apparent surface of magnetic area two, adjacent sector magnet
Property area magnetic differ, the external end head of the strip permanent magnet is the strip shape gob outer end on the small cone of outer diameter and rotor
The conical opening of head matches.Axially extending bore is set on the external rotor of the arcuate permanent magnetic, rotor is lowered the temperature.
The present invention has the advantages that the low and suitable single-piece of price or small lot batch manufacture compared with the prior art.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Technical scheme on rotor as shown in figure 1, be evenly distributed and motor series（Such as quadrupole）It is identical
Radial direction strip permanent magnet 1, near motor axis hole 5 rotor 3 on be evenly equipped with and strip permanent magnet number identical arcuate permanent magnetic
Rotor is divided into four sector shaped magnetic areas, the bar by body 4, the strip permanent magnet of aforementioned four radial direction and four arc-shaped permanent magnets
The two sides of shape permanent magnet have different polarity（N、S）, the inside and outside arcwall face of the arc-shaped permanent magnet has different polarity
（N、S）, the magnetic requirements in composition sector shaped magnetic area are, the magnetic and arc on the relative surface of two adjacent radial direction strip permanent magnets
The magnetic all same of the outer surface of shape permanent magnet, such as N poles, the magnetic area are N poles magnetic area, it is desirable to the magnetic of adjacent magnetic area
Property is far from it.In order to improve the periphery of the performance of permanent magnet, four outer faces of the strip permanent magnet being radially arranged and rotor
Face maintains an equal level, and the external end head of strip permanent magnet is provided with the conical opening phase of the small cone of an outer diameter and rotor strip shape gob termination
Match somebody with somebody, the effect one of this cone structure is enhancing permanent magnet performance, and two is that permanent magnet is thrown out of when preventing motor from rotating.Each bar
Shape permanent magnet should try one's best and reduce destruction to squirrel-cage bar 2, axially extending bore 6 be set on the external rotor of each arcuate permanent magnetic, during work
Lower the temperature beneficial to rotor.
Strip permanent magnet axially can be interted into by spliced together with arc-shaped permanent magnet 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, is bonded with secondary operation adhesive, last block fritter strip permanent magnet, and 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.
