Description
Technical field
The utility model relates to technical field of motors, is specifically related to a kind of novel high-speed electric expreess locomotive.
Background technology
Motor is all very important power-equipment in industrial production and people's lives, and the power consumption of motor also ranks first at various electric equipment meta simultaneously.In global range, the power consumption of motor accounts for more than 50% of world's total electricity consumption, accounts for about 70% of industrial electricity; Account for 60% of total electricity consumption at the power consumption of China's motor, and the efficiency of current China motor is generally much lower than developed country, the efficiency of motor also has very large room for promotion.The efficiency of managing to improve motor can energy savings to a great extent, reduces the discharge of greenhouse gas.It is estimated that, if all use high-efficiency electric motor in the year two thousand twenty China, the CO discharged in air every year
2and SO
22.6 hundred million t and 78.9 ten thousand t can be reduced respectively.In today that the increasingly in short supply and environmental problem of the energy is on the rise, reduce the loss of electric machine, improve electric efficiency not only energy savings, control environment to pollute etc. in be significant, and imperative.
High-speed electric expreess locomotive in current China market is widely used, but it also exists certain weak point, and such as, stator adopts silicon steel sheet to make, and production cost is high, and it is high to consume energy, and the loss of motor is high, but efficiency is lower, also have impact on rotating speed to a certain extent.In addition, current high-speed electric expreess locomotive is when dispelling the heat, and only by a fan cooling, limitation is comparatively large, and radiating effect is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of novel high-speed electric expreess locomotive, and its structure is simple, novel in design, can solve the weak point of background technology.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises housing, support, main shaft, coil, Fe-based amorphous alloy stator and iron core, rotor, permanent magnet, radiator fan, air inlet and hood, one end of housing is installed with support, in housing, level is coaxially installed with main shaft, the middle part outer wall of main shaft is provided with rotor, rotor outer wall is closely provided with permanent magnet, the inwall of housing is closely provided with Fe-based amorphous alloy stator and iron core, Fe-based amorphous alloy stator and iron core are provided with coil, Fe-based amorphous alloy stator and be provided with air gap between iron core and rotor, the other end of housing is provided with hood, main shaft in hood is provided with radiator fan, and the end face of housing is provided with air inlet.
As further improvement of the utility model, uniform ventilation hole on described support, ventilation hole, Fe-based amorphous alloy stator and the air gap between iron core and rotor and air inlet form heat dissipation wind channel, can play effect of radiator fan to greatest extent.
As further improvement of the utility model, described permanent magnet is ferrite permanent-magnet.
Principle of the present utility model is: stator and iron core adopt Fe-based amorphous alloy to make, and non-crystaline amorphous metal is compared with traditional silicon steel, has higher resistivity and thinner thickness of strip, so core loss can be reduced by 70%-90% when being used as core material.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 1-Fig. 2, this embodiment is by the following technical solutions: it comprises housing 1, support 2, main shaft 3, coil 4, Fe-based amorphous alloy stator and iron core 5, rotor 6, permanent magnet 7, radiator fan 8, air inlet 9 and hood 10, one end of housing 1 is installed with support 2, in housing 1, level is coaxially installed with main shaft 3, the middle part outer wall of main shaft 3 is provided with rotor 6, rotor 6 outer wall is closely provided with permanent magnet 7, the inwall of housing 1 is closely provided with Fe-based amorphous alloy stator and iron core 5, Fe-based amorphous alloy stator and iron core 5 are provided with coil 4, Fe-based amorphous alloy stator and be provided with air gap between iron core 5 and rotor 6, the other end of housing 1 is provided with hood 10, main shaft 3 in hood 10 is provided with radiator fan 8, and the end face of housing 1 is provided with air inlet 9.
Uniform ventilation hole on described support 2, ventilation hole, Fe-based amorphous alloy stator and the air gap between iron core 5 and rotor 6 and air inlet 9 form heat dissipation wind channel, can play effect of radiator fan 8 to greatest extent.
Described permanent magnet 7 is ferrite permanent-magnet.
The principle of this embodiment is: stator and iron core adopt Fe-based amorphous alloy to make, and non-crystaline amorphous metal is compared with traditional silicon steel, has higher resistivity and thinner thickness of strip, so core loss can be reduced by 70%-90% when being used as core material.Due to the low loss characteristic of amorphous alloy material, Fe base noncrystal alloy is widely applied in the field such as transformer and Magnetic Sensor.In the operating frequency range of motor, the loss of Fe base noncrystal alloy can be reduced to 1/3-1/5 of silicon steel, therefore uses non-crystaline amorphous metal to make electric machine iron core and can significantly improve electric efficiency.In power frequency or more under low frequency, the proportion that motor iron loss accounts for total losses is little, and the Bs value of non-crystaline amorphous metal is lower than silicon steel, uses amorphous alloy iron core to become significant for the temperature rise of reduction motor iron loss and iron core.Fe base noncrystal alloy, except low-loss advantage, also has the magnetic permeability of several times, silicon steel.So the exciting current of motor can be reduced to a great extent, and then reduce the copper loss of motor.
The above is only in order to illustrate the technical solution of the utility model and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
