In recent years, the authors have presented several papers concerning the use of permanent magnet motors for the direct drive of cooling tower fans. The goal of this paper is to detail how the technology has evolved, communicate lessons learned from field installations and give the reader a practical guide to the installation and use of this type of motor. An in depth case study is presented detailing installation challenges and solutions for a large permanent magnet direct drive motor.
