This paper investigates non-contact hybrid bearings that use permanent magnets for repulsive force and piezoelectric actuators for position-control. A structurally-improved hybrid bearing is presented. First, the concept of the hybrid bearing is briefly introduced along with previous test results. Then, the newly devised bearing with a decreased gap between rotor and stator is designed and analyzed with FEM to optimize the magnetic forces. Finally, a prototype bearing using the proposed mechanism is fabricated and a control method is discussed.
