Die cast copper rotors for electrical motors

Non-ferrous metals foundry


“ 1/ Increase the efficiency of electrical motors of ~3%, what represents at the worldwide level an energy saving equal to the French production of electricity, namely 13.14 million tons of petrol, 2/ Double the lifetime of electrical machines, 3/ Increase the torque, 4/ Reduce the size of motors, On short term, in order to reduce the global warming, new standards for high efficiency motors will be compulsory (EFF1 in Europe and NEMA Premium in the USA). Our technology, coupled with an optimisation of the stator, increases for example by 5 points the efficiency of a 4kW motor, allowing it to reach the NEMA Premium standard. ”
