Nidec Motor Corporation (NMC), manufacturer of U.S. MOTORS(R) now has two offerings available for the water industry. With the proliferation of variable speed motors in every industry, including the water industry, they felt the need to provide inverter duty motors with features designed to protect against the punishing effects of pulse-width modulation (PWM) waveforms generated by inverters.
In addition to being premium efficient and being manufactured with inverter grade insulation, all U.S. MOTORS(R) vertical hollow shaft inverter duty motors 15HP and larger now include a shaft grounding ring to short-circuit current that can damage bearings. And motors 100HP and larger also include an insulated bearing to prevent circulating bearing currents.
Since not all applications in the water industry require variable speed, NMC offers new U.S. MOTORS(R) brand SINEWAVE OPTIMIZED(R) premium efficiency vertical high thrust motors. These motors, from 7-1/2HP to 600HP, meet the new DOE efficiency requirements, provide a lower cost alternative to inverter duty motors, and provide the construction and reliability that customers have come to expect from the U.S. MOTORS(R) brand.
