Background technique
Motor generally includes motor cylinder (motor casing), two end caps that motor cylinder both ends are arranged in, is arranged in motor cylinder
The structures such as the stator and rotor in portion.When carrying out the assembling of motor rotor construction, need first by skeleton coiling, then by it
Cooperating with shaft, pole pawl, inside race, fan, collector ring etc., existing rotor preparation process, workmanship accuracy is very high, but
It is to be directed to some higher fields of precision requirement such as automobile, it is also much insufficient, and for current production level, meet
The technique of such production is few, even if the difference of the technological parameter of each step also causes under overall step unanimous circumstances
The service performance of motor in the completed is different, and in electric motor of automobile, rotor assembly through rotor assembly assembly when examining, usually
The electrical breakdown of setting is penetrated low, and normal mistake not penetrate by high-intensitive electrical breakdown, it is well known that family-sized car scraps the time limit and newly advise in commercial affairs
The regulation to the non-operation car traveling time limit is eliminated in " the automobile forced Rejection standard " that portion formally issues, while by private savings
Vehicle scraps mileage travelled and is limited to 600,000 kilometers.This time limit that eliminates transfers the method for being limited to standard with milimeter number, greatly
The utilization rate of automobile is improved greatly, and original 15 years systems of scrapping are cancelled, it means that the service life of car is likely to much
Greater than 15 years, if 3 years mileages travelled are 100,000 kilometers, (this setting was the maintenance set released according to most of automobile brand is investigated
Meal estimated for 3 years or 100,000 kilometers), then reaching 600,000 kilometers then needs 18 years, so the electric motor of automobile of the prior art needs
Its installation accuracy, examination criteria are improved to meet the time limit requirement that existing automobile uses.And the production process of rotor assembly
