10-25: Recent Developments in Motor Technology Allow Direct Drive of Low Drift

10-25: Recent Developments in Motor Technology Allow Direct Drive of Low DriftThis paper is a follow up to a paper presented in 2009 concerning the use of permanent magnet motors for direct drive of cooling tower fans. In the previous paper, the authors presented a case study where an existing tower was retrofitted with a motor of this type. After a year in operation, the motor was removed from service, completely disassembled and inspected to determine how it performed in the harsh environment inside the cooling tower. Both
