 In previous research,the homopolar magnetic bearing and the maglev motor using the magnetic bearing were developed for application to an artificial heart. Implantable VAD is subjected to acceleration due to patient movement. For this reason, magnetic bearings must have acceleration resistance performance that allows the rotor to float stably without contact against external acceleration. In this pepar, the acceleration resistance performance of the magnetic bearings and maglev motor was calculated. After that, the acceleration performance of two real machines of magnetic bearing and maglev motor ware evaluated by applying acceleration to the magnetic bearing by sinusoidal excitation using a vibrator. As a result, it was confirmed that the acceleration resistance performance of the magnetic bearing and maglev motor almost coincided with each other in the calculation and real machine experiments.
