Abstract
The utility model relates to a fan for a motor, in particular to a high-efficiency energy-saving fan for a motor. The high-efficiency energy-saving fan for the motor comprises a shaft sleeve (2), and nine fan blades (1) distributed at the periphery of a shaft sleeve shell, wherein the fan blades are arc-shaped and uniformly distributed at the periphery of the shaft sleeve shell along one way, the dip angle of each fan blade is about 38 degrees, the difference of the dip angle is not more than plus or minus 5 degrees. The high-efficiency energy-saving fan blade has reasonable design, a simple structure and high efficiency. The nine arc-shaped fan blades and the special dip angle design are adopted, so that the minimum air inlet loss is achieved. By the proving of the experiment data, for the motors with the same specification, and under the premise of not changing other structures, the efficiency of the motor using the outer fan can be improved by 0.2%-0.32%. By the promotion and the application, the high-efficiency energy-saving fan for the motor is beneficial to energy resource saving, and can generate good economical benefits and social benefits.
Description
Technical field
The utility model relates to a kind of motor and uses fan, particularly relates to a kind of motor and uses energy-efficient fan.
Background technique
Along with the development of society, the energy starved problem highlights day by day.Countries in the world have all proposed to economize on resources, and reduce the strategic objective of energy consumption.China is as world population big country, and shortage of resources is especially serious.Therefore, country puts into effect the civilian-oriented project policy, energy-saving and cost-reducing important performance assessment criteria as local governments at all levels.The motor product that this energy policy will directly guide motor manufacturing enterprise to develop to meet the Huimin efficiency to require.
Motor is widely used in industrial and agricultural production, for the development of Chinese national economy is laid a good foundation.And along with the shortage of electric power energy, the energy consumption problem of motor has become energy-saving and cost-reducing serious obstruction.Motor five lossies account for its rated power ratio and directly determine the electric efficiency height; And mechanical loss accounts for significant proportion in five lossies, and therefore how developing the little motor of the high mechanical loss of radiating efficiency also becomes the key that under the prerequisite that does not improve temperature rise, improves electric efficiency with fan.
The model utility content
The utility model proposes a kind of motor and uses energy-efficient fan.Test shows, the motor of same size, and under the constant prerequisite of other structures, motor uses this external fan efficient can improve 0.2%-0.32%.
The technological scheme that the utility model adopted:
A kind of motor is used energy-efficient fan, comprises axle sleeve (2) and is arranged in axle sleeve shell flabellum (1) all around, and said flabellum is an arc, and quantity is 9, unidirectional being evenly arranged in around the axle sleeve shell, and the inclination angle of flabellum is more or less the same in ± 5 ° about 38 °.
Described motor is used energy-efficient fan, and is high to the different motor center, and the diameter and the motor center height of the external diameter place circumference of flabellum are complementary, and differs to be no more than ± 10mm.
The useful good effect of the utility model:
The utility model motor is used energy-efficient fan, and is reasonable in design, simple in structure, and efficient is high.Flabellum adopts 9, is shaped as arc, adopts unique inclination angle design to make the air intake loss minimum.Test data shows, the motor of same size, and under the constant prerequisite of other structures, motor uses this external fan efficient can improve 0.2%-0.32%.It is applied, and will produce good economic benefit and social benefit.
