At present, there are few extra-high-efficiency geared motors that meet the special hygiene demands of industries such as pharmaceuticals and the food & beverage sector. Often, specialist components have to be specified that will withstand the regular cleaning regimes and guarantee clean operation without risk of contamination.
Bauer – part of Altra Industrial Motion – argues that PMSM machines offer much higher efficiencies than induction motors, even under partial-load conditions. In real applications, they have been shown to achieve energy savings of more than 40% compared to standard asynchronous motors.
The new stainless-steel modular geared motor has surfaces which slope at an angle of at least three degrees to prevent the formation of dirt deposits, and to allow the run-off of cleaning agents and water. The stainless-steel construction eliminates the risk of the hygiene rating being compromised as a result of an impact or prolonged periods of use in heavy washdown environments.
