ABB’s Baldor-Reliance® RPM AC™ synchronous permanent magnet cooling tower motors use laminated finned frame construction to provide a highly efficient, power-dense, package with flange mounting dimensions that can replace the right-angle gearbox and jack shaft installation in many conventional cooling towers. This same technology is offered in conventional, yet power-dense, foot-mounted designs that can replace belt and sheave applications where more vertical mounting space is available. Derived from one of the toughest motor platforms used in the most demanding industrial applications, the RPM AC motor is proven to provide a high level of performance inside a cooling tower’s hot and humid environment.
