This paper discusses the development of low speed, permanent magnet motors and how they can be used in direct-drive applications to eliminate the gearbox, NEMA motor, driveshaft, a nd disc couplings from field erect cooling tower designs. Improved reliability of cooling tower fan drives is now possible due to advancements in motor technology as evidenced over the last 9 years. Case studies are presented where cooling towers have been retrofitted. Design considerations, best practices, performance data, maintenance, air flow considerations and efficiency comparisons will be discussed. Show more
