Nidec Motor Corporation (NMC) has introduced a brushless permanent magnet (BPM) electronically commutated (EC) pump motor with an integrated variable frequency drive and user interface. The PerfectSpeed NEMA 48 pump motor is an energy saving product which is designed to be easy to install and operate. It has been engineered specifically to drive booster and hydronic pumps. Both the motor and drive are manufactured by NMC and are optimized to function together for highly efficient and worry-free operation. The on-board drive regulates pump performance so that maximum efficiency is achieved during normal and peak flow operation. The drive eliminates the need for mechanical components like hydraulic control valves, pump speed controls, and large control panels.
