12-17: Permanent Magnet Direct Drive Motors: Lessons Learned #N/A

12-17: Permanent Magnet Direct Drive Motors: Lessons Learned #N/AIn 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

Lab data will be presented

This paper describes the many points to consider beginning with selection of an optimum operating point and many factors concerning the fans operating environment
