A growing solution for delivering higher efficiency with proven reliability is a pumping system built around a permanent magnet (PM) motor. PM motors operate more efficiently using rare earth magnets that perform with no slip. This translates into lower input power for the same output power, saving on operational costs every time the motor runs. In field trials, motors with 94% efficiency ratings provided an investment payback of less than two years in most long- or continuous-run applications. This white paper gives engineers in the mining, industrial, municipal and agricultural sectors a better understanding of the benefits PM motors deliver.
