Description
Technical field
The present invention relates to a kind of permanent-magnetic synchronous motor rotor, specifically a kind of interior design spiral by original rotor
Shape blade and ventilation hole realize the gas circulation of permanent magnet synchronous motor internal closed space, realize the transmitting of heat.
Background technique
Permasyn morot power factor is high, high-efficient, gradually replaces AC induction motor in many occasions.It is few at present
Number developed country begins to use power source of the permanent-magnet synchronizing traction motor as high-speed railway.To avoid the corruption such as water, dust, iron filings
Motor interior permanent magnets are lost, magneto uses full-closed structure.The permanent magnet traction motor power as used in rail traffic
Usually 500KW or more, calorific value is big, and the permanent-magnet material in rotor is under the mal-conditions such as high temperature, it may occur however that loss of excitation
Possibility.Temperature control is the bottleneck in permanent-magnet synchronizing traction motor use, and the heat radiation power for how increasing rotor becomes urgently
The problem of solution.
The gas of existing permanent magnet synchronous motor internal closed space circulates, and relies primarily on and is mounted on two ends of rotor end face
Cooling fin follows progress heat in space of rotor when rotating together between rotor and end cap to exchange, and larger for calorific value
Rotor outer surface and winding outer surface, gap between the two is smaller, and gas fluidity is poor.
Summary of the invention
Aiming at the problem that heat dissipation of above-mentioned permanent-magnet synchronizing traction motor inner rotator encounters, the present invention provides a kind of reinforcement permanent magnetism
The structure that synchronous motor inner chamber gas circulates.
To achieve the goals above, the invention adopts the following technical scheme:
The shaft of a kind of permanent-magnetic synchronous motor rotor with gas circulatory function, the rotor is equipped with helical blade,
Rotor core and permanent magnet are mounted on helical blade outer.
The rotor includes shaft, helical blade and external splines disk and rotor core and permanent magnet sleeve, described
Along being fixed in shaft in helical blade, external splines disk, rotor iron are coaxially fixed in the shaft at helical blade both ends respectively
The both ends of core and permanent magnet barrel bore are equipped with the internal spline matched with external splines disk, offer ventilation on external splines disk
Hole.
Compared with prior art, the present invention have the utility model has the advantages that
The present invention can accelerate to make to reduce between each position of entire permanent magnet synchronous motor by the air circulation inside motor
The temperature difference, avoid the occurrence of permanent magnet loss of excitation caused by hot-spot, achieve the purpose that indirectly reduce motor rotor temperature.
Detailed description of the invention
Fig. 1 is the assembling structure schematic diagram of helical blade, external splines disk and rotor shaft.
Fig. 2 is rotor core and permanent magnet tube-in-tube structure schematic diagram.
Fig. 3 is the assembling structure schematic diagram of permanent magnet synchronous motor.
Specific embodiment
Technical solution of the present invention is further elaborated below by embodiment.
Embodiment 1
The shaft 1 of a kind of permanent-magnetic synchronous motor rotor with gas circulatory function, the rotor is equipped with helical blade
2, rotor core and permanent magnet are mounted on 2 outer of helical blade.
The rotor includes shaft 1, helical blade 2, external splines disk 4 and rotor core and permanent magnet sleeve 3, described
Along being fixed in shaft 1 in helical blade 2, it is coaxially fixed with external splines disk 4 respectively in the shaft 1 at 2 both ends of helical blade, turns
The both ends of 3 inner cavity of sub- iron core and permanent magnet sleeve are equipped with the internal splined hole 6 that matches with external splines disk 4, on external splines disk 4
Offer venthole 5.
External splines disk 4 and the matching relationship between the two of internal splined hole 6 are spline tooth top interference fit.
When electric motor operation, rotor core and permanent magnet sleeve 3 generate turning moment, transmit torque to rotor by spline
1 part of shaft, be output to outside motor.
The centre of rotor shaft part is spiral flabellum, and when permanent magnet synchronous motor work, flabellum is in company with shaft 1 one
With rotation, so that the gas of one end of rotor moves to the other end under the action of spiral sector.Meanwhile the other end
Gas returns to one end, completes circulating for gas by the gap between rotor and stator.The heat that rotor generates is logical
It crosses casing and end cap sheds.
In figure, 7 be stator winding, and 8 be outer air duct, and 9 be interior air duct, and 10 be motor housing.
