Motors acc. to NEMA
NEMA motors (National Electrical Manufacturers Association) for the North American market distinguish themselves as a result of their dynamic design – and especially as a result of their efficiency. The motors with copper die-cast rotor offer NEMA Premium Plus efficiencies that are above the NEMA Premium Standard and currently are the highest available in the market. The generation of general purpose and severe duty NEMA motors will be available in frame sizes 140 to 440 with power ratings of between 1 and 400 HP (Horse Power).
