Sealed bearings minimize the generation of airborne particulates which may be
disadvantageous in clean rooms or controlled environment areas. These
bearings require no maintenance.
2.6.3 Motor
The Innova 4000 Shaker uses a 3-phase brushless ball bearing DC motor. This
low profile motor provides high torque along with quiet, efficient operation
and low maintenance. The motor has a rating of 1/15 horsepower.
