摘要

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, and 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 of operation. A Case study is presented where a cooling cell has been retrofitted. Design considerations, performance data, maintenance practices and material costs will be reviewed. Air flow considerations and efficiency comparisons will also be discussed.
