Balance Pit Construction Project

Between September 2014 and February 2016 Brush Aftermarket built our balance pit. Here's a 5 minute video of that process.  

On May 12, 2017 we dedicated the balance pit to the memory of Edward Sisson.  Eddie was a highly respected and valued team member of Generator and Motor Services until his passing in 2010.   

Balance Pit Spin Process

Here's a small example of what our pit can spin.  Our balance pit can accommodate rotors or motors up to 510 inches (42.5 feet) in length!
