MACHINING QUICK TIPS: Eibenstock Motors FAQ

CLIMAX BB5000 Line Boring Machine Eibenstock Motors FAQ
By David Briggs, Sr. Controls Engineer at CLIMAX – November 2021

The electric drive used on the CLIMAX BB5000 line boring machines uses an Eibenstock EAU 34/4 motor for the rotational drive. These motors produce relatively high horsepower in a small package. While this is good, the downside is that the motors produce a lot of heat and can have trouble dissipating that heat, primarily when running under high loads and at slow speeds. This is true of all series-wound motors like this, such as Milwaukee, Husqvarna, and Dewalt. To get the best service life out of your motor, you should run the motor at the highest speed possible.

The Eibenstock EAU 34/4 motor has a 4-speed gearbox. For each BB5000 line boring machine setup, select the lowest gear you can (highest motor speed). Try to always run the motor at no lower than 50% of full speed when under heavy loads—the more cooling air passing through the motor, the better.
