TEC Force Ventilation Fan for a 110 Framed Electric Motor, 2800 RPM, 230/1/50 Supply Voltage

Description

There is an increasing need for variable speed drive applications for motors with enhanced cooling while running at low speeds. Closed-loop AC inverters are supplied at zero speed by 100% motor speed. A second, small, constant speed motor for driving the cooling fan is the easiest way to get this done. The use of force ventilated or blown separate engines is not new, but new concepts are being introduced with the advent of static frequency inverters. A forced ventilation system must be used to provide the required cooling system in the motor body. Inadequate cooling contributes to: loss of power, and premature failure.
