IntroductionThe current centering device for the bushings and magnets has several flaws which cause problems for the LVAD heart pump. The following page illustrates how the current test rig is used. A step by step procedure of the process in centering the bushings and magnets has been documented and provided.

Physically holding the bushings and magnet
This is the first procedure to the centering of magnets. Because the test rig has 5 degrees of freedom, the linear slide are not aligned therefore before each test a person needs to adjust the stages aligning the slides using a precision machined rod to insure that the slides are aligned. This is time consuming and cumbersome.
The next step is determining the physical run out of the bushing and magnet. The purpose of this is to determine how off center the bushing and magnet are from the axis of rotation. The problem with this step is human error in reading both dial indicators and recording there value.
