Abstract
A kind of magneto cooling end cap, includes at least one piece of semiconductor chilling plate suitable with end cap size.Described end cap is followed successively by inner side fin, inner side semiconductor chilling plate, intermediate supports flat board, outer semiconductor cooling piece and outside fin inside motor to outside.The present invention can accelerate the heat of motor internal is delivered to outside motor, reaches to cool down the purpose of rotor.
Description
Technical field
The present invention relates to the non-transmision end end cap of a kind of motor, specifically a kind of by installing half additional at original end cap two ends
Conductor cooling piece and fin, by actively transferring to the heat that motor internal rotor produces outside motor from outside input electric energy
Portion.
Background technology
Permasyn morot power factor is high, and efficiency is high, progressively replaces AC induction motor in many occasions.The fewest
Number developed country begins to use permanent-magnet synchronizing traction motor as the power source of high-speed railway.For avoiding the corruption such as water, dust, iron filings
Erosion motor internal permanent magnet, magneto uses full-closed structure.Due to the permanent magnet traction motor power used in track traffic
Usually more than 500KW, caloric 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 on permanent-magnet synchronizing traction motor uses, and the heat radiation power how increasing rotor becomes urgently
The difficult problem solved.
Summary of the invention
Use the bottleneck run into for above-mentioned permanent-magnet synchronizing traction motor, the present invention provides a kind of and strengthens permanent magnet synchronous electric
The end cap of machine rotor heat-sinking capability.
To achieve these goals, present invention employs techniques below scheme:
A kind of magneto cooling end cap, includes at least one piece of semiconductor chilling plate suitable with end cap size.
Described end cap be followed successively by outside inside motor inner side fin, inner side semiconductor chilling plate, intermediate supports put down
Plate, outer semiconductor cooling piece and outside fin.
Described intermediate supports flat board circle centre position installs the bearing block of motor bearings.
The surface of described inner side semiconductor chilling plate and outer semiconductor cooling piece is coated with silicone grease.
Inside described inner side fin, intermediate supports flat board and outside, fin is fixed with motor case by bolt.
Fin fin inside motor internal side and outside in described inner side is provided with near outside motor side
A plurality of radiating ribs.
Described inner side semiconductor chilling plate and outer semiconductor cooling piece be all cold end towards motor internal, hot junction is towards electricity
Outside machine.
Compared with prior art, the beneficial effect that the present invention possesses:
The present invention can accelerate the heat of motor internal is delivered to outside motor, reaches to cool down the purpose of rotor.

Detailed description of the invention
Below by embodiment, technical scheme is further elaborated.
Embodiment 1
A kind of magneto cooling end cap, includes at least one piece of semiconductor chilling plate suitable with end cap size.
Described end cap is followed successively by inner side fin 1, inner side semiconductor chilling plate 2, intermediate supports inside motor to outside
Flat board 3, outer semiconductor cooling piece 4 and outside fin 5.
Described intermediate supports flat board 3 circle centre position installs the bearing block 6 of motor bearings.
The surface of described inner side semiconductor chilling plate 2 and outer semiconductor cooling piece 4 is coated with silicone grease.
Inside described inner side fin 1, intermediate supports flat board 3 and outside, fin 1 is solid with motor case by bolt
Fixed.
Described inner side fin 1 fin 1 inside motor internal side and outside sets near outside motor side
There is a plurality of radiating ribs 8.
Described inner side semiconductor chilling plate 2 and outer semiconductor cooling piece 4 are all cold ends towards motor internal, hot junction towards
Outside motor.
Embodiment 2
Assume that a permanent magnet synchronous motors actual power is 300kw, iron loss is power 1% that rotor produces, i.e.
3kw.Assume that the heat produced all is spread out of by end cap, then the refrigeration work consumption of semiconductor chilling plate is 3kw.If semiconductor refrigerating
The cop Energy Efficiency Ratio of sheet is 80%, then the input power of semiconductor chilling plate is 3.75kw, and the heat of discharge is 6.75kw.End cap
The temperature difference at two ends is about 30 °.Along with the progress of science and technology, the particularly development of material science, the iron loss of magneto will progressively
Reducing, the cop value of semiconductor chilling plate increases.Electric motor end cap with refrigerating function has the biggest development space.
Operation principle:
When motor runs, the heat of rotor is delivered in the middle of the space of motor internal by the radiating ribs 8 on rotor,
Absorbed by the inner side fin 1 of end cap.The heat of inner side fin 1 is delivered to centre by the inner side semiconductor chilling plate 2 of end cap
Supporting flat board 3, the heat of intermediate supports flat board 3 is delivered to outside fin 5 by the outer semiconductor cooling piece 4 of end cap, passes through
The common effect of two-stage cooling piece, is dispersed in the air of outside motor.Outside the turbine fan 7 being connected with electric machine main shaft is accelerated
The wind speed of portion's fin surface, strengthens heat-sinking capability, it is ensured that motor plays the highest service efficiency in the secure state.
