W40 Open Induction Motors
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. The W40 line meets or exceeds the efficiency levels determined by the International Standards and the minimum efficiency level programs in force worldwide.
Technical characteristics:
- output: 11 kW to 1 400 kW;
- number of poles: 2 and 4;
- frequency: 50 Hz;
- voltage: 208 to 4 160 V;
- frames: 160 L to 450 K/J;
- color: RAL 5009 – blue.
Features:
- high performance, because the open enclosure allows more compact design for the same output compared with totally enclosed motors, resulting in the most cost–effective option for the driven equipment;
- WEG is now introducing frames sizes 355, 400 and 450 in W40 portfolio. This represents an important improvement in the offered rated output, from the previous 370 kW to 1,400 kW in 50 Hz (600 to 2 250 HP in 60 Hz). This new range features an entirely new concept, offering low noise levels, improved mechanical stiffness and heat dissipation. The introduction of the design allowed WEG to offer the W40 motors in medium and high voltage ratings, being available up to 6,6 kV;
- the innovative design of the new fans system combined with the new frame concept, ensure to the W40 motors maximum air flow with reduced noise levels;
- modular construction enables easy and quick transformation among all possible configurations;
- WISER insulation system increases stator electrical strength and allows the motor operation by frequency inverters, without damage by voltage peaks.
Applications: pumps, compressors, fans, exhausters, kneader and mixer machines, cutting and sawing machines, presses, industrial machines, conveyors, blowers, cranes, packaging equipment and other sheltered and protected industrial environment applications.
