What do power systems for hybrid vehicles and cooling towers have in common? Perhaps their drive trains and controllers, according to Baldor Electric Co. Hybrids use a permanent magnet direct-drive motor linked to a variable speed controller. Now Baldor has come out with a similar system for cooling tower fans.
The company's new RPM AC cooling tower motor and VS1CTD variable speed controller were developed specifically for the application. According to Baldor, the combination of laminated steel finned frame construction and high strength permanent magnets yields a motor that has significantly better power density, torque (especially at partial loads), and ...
