CAST COPPER ROTOR

Cast copper rotor is a new type of motor rotor based on copper as a conductive substrate, which utilizes theexcellent conductivity of copper to reduce rotor loss and improve motor efficiency.Compared to traditional aluminumrotor motors, cast copper rotor motors have the following advantages.

1. lmprove efficiency. Replacing aluminum rotors with cast copper rotors can significantly improve the efficiency ofsmall and medium-sized motors, resulting in abundant energy saving benefits.Taking the Y132M4 7. 5KW motor asan example, after replacing the cast copper rotor,the motor efficiency increased from 87%to 90.4%..According to thecalculation of using the electric motor for ten vears,it can save 16080 yuan in electricity costs,which is 16 times thereplacement cost,and the benefits are very obvious.At present,a copper rotor induction motor with IE5 efficiency levebeen developed,and the measured efficiency of the 15HP-4P motor can reach 93.6%.has2. Reduce temperature rise.Taking the 25HP 18.7Kw motor as an example,using a copper rotor motor reducesthe temperature rise by 41%compared to an aluminum rotor motor,only 47.2'℃.And for every 10 degrees Celsiusdecrease in the operating temperature of the motor, its service life can be doubled, therefore,copper rotor motors caneffectively extend the lifespan of the motor At the same time,it also increases electrical safety,especially suitable forexplosive special environments.

3. Reduce volume, weight, and cost,Under the same efficiency, the volume of the cast copper rotor motor isreduced by about 15%compared to the aluminum rotor motor, making it suitable for the application of reducerscompressors, ad pumps.By optimizing the desigu, the welght ot the cast copper rotor motor can be reduced bv about20%. For example, after converting a 15 HP TEFc motor to a cast copper rotor, the total weight is reduced by 8KG. Inters of cost,a cast copper rotor motor with the same efficiency can reduce it by about 10%. when the price of copperdecreases or the price difference between copper and aluminum decreases, the cost reduction will be more significant4.vorroslon resistance.vopper has excellent corrosion resistance,making 1t very sultable tor appllcatlons suchas brine pumps and hot water circulation pumps, "his product is widely used in souirrel cage induction motors in variousfields such as industry, home appliances, aviation, navigation, and military.
