Abstract
The utility model discloses a kind of 200kW lightweight generator, mainly comprise front end housing, stator, rotor, rear end cap and exciter stator; It is characterized in that: front end housing and rear end cap are all contained on stator, rotor is contained on front end housing and rear end cap; Front end housing and rear end cap adopt cast aluminium alloy part, and band winding exciter stator iron core forms exciter stator with rear end cap, and the stator winding span circle double-layer overlapped winding such as adopt the employing of 3/4 pitch, coil pattern not, described generator, without casing, is single supporting construction.The technique effect of the utility model patent is: structure is simple, easy to make, be applicable to 200kW lightweight generator, alleviates the weight of generator when meeting performance.
Description
Technical field
The utility model relates to a kind of generator, is specifically related to a kind of 200kW lightweight generator.
Background technology
Vehicle power is power inverter again, is a kind ofly DC12V direct current to be converted to the AC220V alternating current identical with civil power, for general electrical equipment, is one power supply changeover device easily, gains the name owing to being usually used in automobile.Along with the high speed development of information, communication, vehicle power have also been obtained development at a high speed, and because vehicle load is limited, this just requires that the weight of generator is more light better when meeting performance.
Summary of the invention
The purpose of this utility model is to provide a kind of 200kW lightweight generator, alleviates the weight of generator when meeting performance.
The technical solution of the utility model is: a kind of 200kW lightweight generator, mainly comprises front end housing, stator, rotor, rear end cap and exciter stator; It is characterized in that: front end housing and rear end cap are all contained on stator, rotor is contained on front end housing and rear end cap; Front end housing and rear end cap adopt cast aluminium alloy part, and band winding exciter stator iron core forms exciter stator with rear end cap, and the stator winding span circle double-layer overlapped winding such as adopt the employing of 3/4 pitch, coil pattern not, described generator, without casing, is single supporting construction.
Employing cast aluminium alloy part described in the utility model can alleviate generator weight, half fewer than ironcasting weight; Stator winding span adopts 3/4 pitch, coil pattern to adopt the circle double-layer overlapped winding such as not, is to meet the requirement (require line voltage-form distortion rate≤3%, phase voltage waveform aberration rate≤5%) of generator to weight and unloaded irregularity of wave form.
Its performance characteristics of engine described in the utility model is that users of power requires overload 10%, actual power is 220kW, weight user requires to be not more than 715kg, line voltage-form distortion rate is not more than 3%, phase voltage waveform aberration rate is not more than 5%, and the performance index that other performance meets generator are not less than or are better than the regulation of GB/T 15548-2008 " the three-phase synchronous generator general technical specifications that reciprocating internal combustion engine drives ".The generator weight existing market meeting this performance is all greater than 760kg.
The technique effect of the utility model patent is: structure is simple, easy to make, be applicable to 200kW lightweight generator, alleviates the weight of generator when meeting performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings: 1, front end housing 2, stator 3, rotor 4, rear end cap.
Embodiment
The utility model comes work and enforcement like this, and a kind of 200kW lightweight generator, mainly comprises front end housing 1, stator 2, rotor 3 and rear end cap 4; It is characterized in that: front end housing 1 and rear end cap 4 all fill on the stator 2, rotor 3 is contained on front end housing 1 and rear end cap 4; Front end housing and rear end cap adopt cast aluminium alloy part, and stator winding span adopts 3/4 pitch, coil pattern to adopt the circle double-layer overlapped winding such as not; This motor is without casing, and the heavy 760kg(of the motor on existing market is containing box weight 20kg).
Front end housing 1 and rear end cap adopt cast aluminium alloy part, and under the prerequisite of proof strength, its weight reduces to 23.3kg by ironcasting 55kg.Winding takes 2/3 pitch can better meet the requirement of irregularity of wave form, but winding coefficient is low only has 0.829, and iron core is longer, can not meet weight demands.Winding takes 5/6 pitch winding coefficient Gao Keda 0.925, and iron core is shorter but can not meet the requirement of phase voltage waveform aberration rate, and winding takes 3/4 pitch winding coefficient to be 0.885 requirement that can meet voltage-form distortion rate and weight.This motor does type approval test motor performance after having manufactured experimently and weight all meets the demands, motor weight 710kg, and phase voltage waveform aberration rate is 4.8%, and line voltage-form distortion rate is 1.4%.
