The IE5 ultra-premium SynRM motors from ABB offer up to 50% lower energy losses and significantly lower energy consumption than the commonly used IE2 induction motors, says the company. ABB first introduced SynRM technology in 2011 and it says that case studies in industrial installations have demonstrated energy savings of up to 25%, depending on the application. The IE5 level of efficiency is made possible by the SynRM design which combines the performance advantages of permanent magnet technology with the simplicity and service-friendliness of an induction platform. To ensure an environmentally friendly design, the motors do not feature rare earth materials.
