Description
Technical field
The present invention relates to rotor design technical field, more particularly to a kind of permanent magnet machine rotor.
Background technology
Magneto widely uses because with efficiency high, the low advantage of power consumption, the rotor of common magneto
Magnet steel is externally embedded type, i.e. magnet steel is in the rotor punching peripheral groove, and rotor punching is full circle piece, such a structure
The problems such as interelectrode magnetic leakage, stuffy be present, these problems can all influence motor performance, reduce the work of motor
Efficiency and service life.
The content of the invention
The purpose of the present invention is the defects of overcoming prior art to exist, there is provided one kind reduces leakage field, improved
The permanent magnet machine rotor of electric efficiency.
The technical solution adopted for the present invention to solve the technical problems is：A kind of permanent magnet machine rotor, bag
Include more than two annular rotor punchings, rotor punching is superimposed together and is set in the outer of rotor core
Portion, magnet steel is interspersed between rotor punching, and the edge of rotor punching sets breach, rotor punching overlapping
Rotor pressing ring is set to fix rotor punching into cylindricality and at the both ends of cylindricality.
Beneficial effect：Magnet steel in the present invention is interspersed between rotor punching, can effectively reduce leakage field,
In addition, the setting of breach make it that the air of rotor outer periphery is circulated, magneto work is effectively reduced
When temperature, avoid the performance of the excessively high influence magneto of leakage field, temperature, effectively improve Permanent Magnet and Electric
The operating efficiency and service life of machine.
Brief description of the drawings
Fig. 1 is the half sectional view of the present invention.
Embodiment
With reference to Fig. 1, the invention will be further described.
A kind of permanent magnet machine rotor, including more than two annular rotor punchings 10, rotor punching 10
It is superimposed together and is set in the outside of rotor core 20, magnet steel is interspersed between rotor punching 10
30, the edge of rotor punching 10 sets breach 11, and rotor punching 10 is overlapped into cylindricality and in cylindricality
Both ends set rotor pressing ring 40 rotor punching 10 is fixed.Magnet steel 30 in the present invention is interspersed
Between rotor punching 10, leakage field can be effectively reduced, in addition, the setting of breach 11 causes outside rotor
The air in week is circulated, and is effectively reduced temperature during magneto work, is avoided leakage field, temperature mistake
The performance of high influence magneto, effectively improve the operating efficiency and service life of magneto.
As further preferred scheme：More than two through holes are opened up in the rotor punching 10,
The hole position face of the through hole of adjacent rotor punching 10, the through hole of hole position face are superimposed together to be formed
Passage, magnet steel 30 are two or more, and magnet steel 30 passes through from the passage, wherein, magnet steel 30
Number depending on the size of magnetic needed for rotor in magneto.
Further, the breach 11 is V-type, and breach 11 is two or more, and adjacent rotor rushes
The position face of breach 11 of piece 10, breach 11 are superimposed together to form a ventilating duct, ensure work
The inside of magneto being capable of timely ventilation and heat when making.
It should be appreciated that specific embodiment described above is only used for explaining the present invention, it is not used to limit
The fixed present invention.The obvious changes or variations extended out by the spirit of the present invention is still in this hair
Among bright protection domain.
