W22 NEMA Premium Efficiency - 3 Phase - TEFC - Footless - C-Flange

High performance with maximum energy efficiency, this is the goal of the new WEG electric motor. High efficiency and low cost of ownership throughout the entire motor lifetime have been the basis for the W22 development. A design created to maximize performance and energy savings.

WEG's W22 cast iron platform has an improved cooling system and solid feet for cooler operation and reduced vibration and noise, extending the life of the motor.

• Rolled steel frames are inverter (VFD) rated (2:1 CT and 10:1 VT)
• 50/60 Hz rated (380 V on nameplate - 400/415 available)
• Rated 50 Hz at same horsepower up to 250 HP 1.0 service factor for 2, 4 & 6 pole motors
• Rated 50 Hz at same horsepower up to 125 HP 1.0 service factor for 8 pole motors
• Class F insulation (impregnation resin and magnet wire are Class H)
• F1 mounted (cast iron frames are F2 convertible). Frames 447T and up can easily be F2 converted by simply rotating the terminal box adapter.
• Stainless steel nameplate - laser etched with high contrast background (cast iron frames only)
• Cast iron frames - regreasable ball bearings (frames 254T and up)
• Rolled steel frames - ZZ ball bearings permanently lubricated
• Gasketed conduit box
• Class I, Div. 2, Groups A, B, C & D – T3, Class II, Div 2, Groups F & G – T3C (cast iron frames only)

Features That Make a Difference (cast iron frames):

• 1.25 service factor up to a 100 HP
• Optimized ventilation system for cooler operation and reduced noise levels
• Solid base for reduced vibration levels
• Frames 447T and up can easily be F2 converted by simply rotating the terminal box adapter
• NPT threaded terminal box
