Abstract

This paper proposes a novel structured 3-DOF(Degree-of-Freedom) spherical motor. 3-DOF spherical motor presents some attractive features by combining pitch, roll, yaw motion in a single joint. The proposed motor has pole which is electromagnetic in stator and rotor. poles produce magnetic flux through by exciting current then produce torque. We show a novel structured rotor to avoid mechanical overlapping of each coil in rotor. The validity of the analysis is confirmed by 3D finite element method.
