Motor Technology
Motor technology chosen for store building applications plays a big role as well. The optimal companion to variable speed drive is a high efficiency motor like ABB’s IE5 synchronous reluctance motor (SynRM). Compared to an IE3 energy efficiency class induction motor, it offers up to 40 percent reduced energy losses. This makes SynRMs the new first choice to meet the growing global demand for improved energy efficiency. Synchronous reluctance motors offer even higher project sustainability in comparison to other motor technologies thanks to no rare earth magnets in the motor design. The reliability is also increased. SynRM technology offers up to 30°C lower winding temperatures and up to 15°C lower bearing temperatures, which prolongs the motor lifetime and reduces the need for maintenance.
