The International Electrotechnical Commission (IEC) establishes certain standards related to efficiency, power output and size for motors. Nidec Motor Corporation is a leading name in the motor industry, and your company can count on our IEC motors. With our U.S. MOTORS® brand pedigree dating back over 100 years, we’re well-versed in producing IEC motors that are efficient, reliable, and IEC-compliant. 

NEW IEC Models are now launching and in stock! 

Our new IEC models excel at meeting efficiency and energy output standards. A full stock offering is available at our Southaven, MS warehouse including:
