Thermal Performance of Induction Motors for Washdown Environment

摘要

Some specific applications fields of electric motors, such as Food and Beverage (F&B) applications, require highly demanding hygiene procedures that involve a highly aggressive environment for the motor, including e.g. frequent high pressure and high temperature washing with water or more aggressive detergents. Specific materials and protection features are used in motors to better withstand such environment, however these have an impact on performance and lead to oversized machines. This paper describes some solutions and their impact on performance, with specific focus on the thermal properties of the analyzed machine.
