WEG WIN Cast Iron TEFC

The WEG WIN Cast Iron TEFC Induction Motor is a robust, energy-efficient solution designed for industrial applications demanding durability, performance, and long service life. Engineered with WEG’s advanced WISE® insulation system, this motor is available in IE2 (High Efficiency), IE3 (Premium Efficiency), and IE4 (Super Premium Efficiency) classes. It offers outstanding thermal performance, superior mechanical strength, and long-term reliability in demanding environments. With rated outputs from 0.18 to 500kW, support for multiple pole configurations (2, 4, 6, and 8), and TEFC (Totally Enclosed Fan Cooled) construction (IC411), this motor is ideal for continuous-duty operations (S1). The IP55 protection and Class F insulation make it suitable for ambient conditions up to 50°C and 1000 m.a.s.l.
