How do end users make repair or replace decisions for failed electric motors?  This question was explored in EASA’s 2014 end-user customer research study. It was also examined in the earlier 2003 and 2008 research projects providing the opportunity to determine if attitudes and practices have changed over time.

In the most recent study, half of the end users surveyed reported a policy of automatically replacing motors un­der a specified horsepower rating. The specific rating ranged from as low as 1 hp to over 200 hp, with the median rating of 10 hp.
