A novel 5-DOF actively controlled self-bearing motor that combines the functions of a motor, two radial AMBs, and an axial AMB has been developed to achieve smaller size and higher performance simultaneously. In this paper, prototype 5-DOF self-bearing motor is evaluated by static and dynamic experiments. First, the fundamental performance of the 5-DOF self-bearing motor such as the motor torques, the radial and axial control forces and the tilt control torques are measured. Second, the dynamic performance was tested by measuring the step responses and the frequency responses. Finally, the maximum oscillation amplitude and power consumption are measured during rotation without any contact. The results showed high feasibility of the proposed 5-DOF self-bearing motor.
