W40 Open Induction Motors The W40 motor is a general purpose line designed for environments where dirt and moisture are minimal. The W40 cast iron frame is designed to provide maximum ventilation and heat dissipation, offering low vibration levels, high mechanical stiffness and durability. Widely used in applications such as compressors, pumps and chillers, the W40 line meets or exceeds the efficiency levels determined by International Standards and the minimum efficiency level programs in force worldwide. Standard Features  Rated output: NEMA (60 Hz) - 15 to 2,500 HP  Number of poles: 2 and...

Definite Purpose Lines WEG, with its massive product portfolio, offers several lines from the cast iron W40 mechanical platform such as Close-Coupled Pump Motors (JM/JP), Oil Well Pumping Motors (Design D, high slip), fire pump motors and Compressor Duty Motors. These definite purpose lines take advantage of all W40 benefits and are specifically designed to perfectly suit all applications needs. New NEMA L5010, L5810, L6808/09 Frame Size WEG is now introducing frames sizes L5010, L5810, L6808/09 in W40 portfolio. This represents an important improvement in the offered rated output, from the previous...
