COOLING TOWER MOTORS Three-Phase TEFC & TEAO Air Handling Motors WEG’s cooling tower motors are designed for operation in 100% humidity and the most corrosive environments. They designed to operate in either horizontal or vertical mounting. 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.
Standard Features: • 50/60 Hz rated (380V on Nameplate - 400/415 Available - Same Horse Power at 50 Hz with a 1.0 service factor) • Class F insulation (Impregnation Resin and magnet Wire are class H) • Standard mounting is F2. F1 mounted motors are identified in the part number. (Both configurations are convertible). Frames 447T and up can easily be converted by simply rotating the terminal box adapter • Stainless Steel Nameplate - Laser etched with high contrast background • Double Sealed bearings
Features that make a difference: • 1.25 service factor • Multiple endbell drain plugs for shaft up, down or horizontal mounting • Drain plugs in terminal box • Rubber lead separator between terminal box and frame • Internally and externally epoxy painted • Double sealed bearings • Double impregnation and bake
Cooling Tower - NEMA Premium Efficiency - Three Phase -TEFC/TEAO WEG’S Cooling Tower - NEMA Premium Efficiency motors meet or exceed all EISA2007 requirements for energy efficiency. These TEFC and TEAO motors are built according to NEMA standards and designed for operation in 100% humidity and the most corrosive environments. The entire line is Inverter Rated for use with Variable Frequency Drives. They are designed to operate in either horizontal or vertical shaft up/down position. Sealed bearing in all sizes require no lubrication. As with any other WEG motor, Cooling Tower motors are tested in accordance with IEEE 112, Method B, and their efficiency values are certified by UL (CSA C390). Cooling Tower motors will meet Design B torques, maintaining exceedingly high breakdown and locked rotor torque while providing the highest rated efficiency levels.

All single-speed premium efficiency models meet NEMA®† premium efficiency levels ● Thousands of configurations to choose from VBXX seals are installed on the "wet" end of the high-efficiency motor The rotor balance of the high-efficiency motor is better than 0.08 inches/second ●Comply with IEC 34-5 grade IP55 Inverter duty cycle and two-speed models help customers meet ASHRAE standard 90.1
The motor is a new generation of cooling tower special three-phase asynchronous motor matched by our company. Its design concept and structure type are integrated into the new scientific research achievements of our company in the cooling tower motor industry over the years, and the use environment of the cooling tower motor is fully considered. In terms of sealing, moisture resistance, water resistance, reliability, etc., it is reasonably matched with the cooling tower, and fully meets the outdoor protection requirements for long-term operation in humid and hot environments. The product has reached the international advanced level and is a new type of cooling tower motor.
The motor adopts two installation types: IM V30 and IM V1:
IM V30 type: The machine base has no feet and is fixed by the direct-connected bracket, which is used for direct-connected fans.
IM V1 type: The machine base has no feet, the end cover has a flange, and it is equipped with a reducer.
The motor rating is a continuous rating based on the continuous duty system S1, and the protection level is IP54.
