MOTORS ACCORDING TO THE NEMA STANDARD

Motors According to the NEMA Standard Powerful, Robust, Reliable We manufacture low-voltage motors according to the NEMA standard for a wide range of applications to comply with the local specifications of the North American market. Ranging from motors designed to the EPACT regulations of the USA (specified minimum efficiencies) through IEEE-841 and motors with NEMA Premium efficiencies: our NEMA motor series guarantee maximum operational reliability and a long service life. Designed and manufactured for rugged operation, our NEMA motors can cope with the harshest industrial conditions - strictly complying with the international quality standard DIN EN ISO 9001, with maximum performance for the best possible reliability and efficiency.
