Machine oil has cooling, lubrication, cleaning, seals four big functions, and it plays vital effect for ensureing that electromotor works normally. Electromotor in the running, if some friction positions can not get suitable lubrication, will produce dry friction. It was verified that the heat that dry friction produces at short notice is enough to make metal molten, the damage that causes parts even stuck (many leak or the fault such as scuffing of cylinder bore, axle suspension bush occurs in the automobile of leakage of oil, main cause is that this). Therefore good lubrication must be given to the friction position in electromotor. When after lubricating oil stream to friction position, one layer of oil film of formation on friction surface will be sticked to, reduce the resistance between friction parts, and oil film strength and toughness are the keys playing its lubrication. The heat that fuel produces after burning in electromotor, only sub-fraction is for the driving of power output and frictional resistance consumption and auxiliary body, all the other major part heats, except being discharged to air China and foreign countries with waste gas, also can be taken away a part by the cooling medium in electromotor.
