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.
