Cooling-tower motor A new electric motor for driving cooling-tower fans features a design that prevents current from flowing through the shaft bearings, allowing longer lifetime and less maintenance. The TEAO motor, made by Marathon Motors Corp. (Wausau, Wis.; www.marathonelectric.com) also has the highest ingress protection (IP) rating for small airborne particles of any fan motor currently available and can be mounted with the shaft at any angle, the company says. It is suitable for use in all HVAC (heating, ventilation and air conditioning) applications and for cooling towers in the power generation and other industries, notes Chris Voll, distribution product manager at Marathon. The motor is available in a range of sizes from 3 to 250 hp.
