Because a car often needs,4 shake window electric machinery, demand is bigger, each leader plant is opposite together with the demand of the oscillatory noise that electric machinery causes is particularly high, the rotate speed that plays in load to electric machinery and locked-rotor torsion wave motion have very firm demand, so electric machinery production introduces full automatic or semi-automatic product line commonly. Shake the core component of window electric machinery is armature, its main shaft is high frequency quench, worm cold extruding (or milling) , alignment, essence is ground outside round, spray of oxygen of chip of armature pressing iron, annulus, pressure commutator, circle vehicle of line, spot welding, fine, report to measure, pair of technology such as dynamic balancing are right the special key such as the wave motion of electric machinery function and oscillatory noise level, and made of baked clay felt of the magnetism on electric machinery assembly line and the online test to electric machinery waterproof properties, load performance and oscillatory noise are to ensure what electric machinery satisfies a client to ask is important assure.

5. technology is characteristic

Shake the rated power of window electric machinery is in commonly 20 ～ 30W, speed ratio 50 ～ 72: 1, according to the requirement of different client system, carry rotate speed to be 60 ～ for nothing 120 turn ／ Min, locked-rotor torsion 7 ～ 16Nm, 35A of ＜ of locked-rotor electric current. Electric machinery basically experiments have life test (- 40 ℃ ～ 80 ℃ ) , experiment of rain test, radio interference rejection, hot protector experiment, from the lock all sorts of experiment, environments expose experiment, card to live experiment, drop test, oscillatory experiment, concussion experiment, demagnetization experiment, insulation resistance. Home basically shakes window electric machinery produces manufacturer to rain of electric machinery of car of Shanghai law Lei Ao blows group of expensive boat of limited company of electric machinery of join forces of harbor of systematic limited company, Zhang Jia, China factory of Electromechanical of 10 thousand rivers. At present the window of certain and dynamoelectric door of the distribute on domestic maintenance market rises fall implement ascendant difficulty of window of burn down of in use occurrence electric machinery, car, noise increases wait for breakdown, one of main reasons are his electric machinery chooses the manufacture in a rough way that goes up with workmanship in raw material, the insulation intensity of electric machinery, surplus power, wear all did not achieve technical standard place to come.

Because shake window electric machinery develops in home very fast, formulate an occupation standard already no time to delay, institute of electrical appliance of car of the closest Changsha and rain of electric machinery of car of Shanghai law Lei Ao blow systematic limited company to combining home to basically make manufacturer formulate occupation standard, this shakes to normative our country the design of window electric machinery, make, the experiment have direct effect. Next watches are the main technique index that drafts medium occupation standard and foreign standard is brief and comparative.
