Outline of Final Research Achievements |
We developed a 3-degree-of-freedom (3-DOF) outer rotor type spherical actuator for spherical joints. It was difficult to evaluate the torque characteristics of the 3-DOF spherical actuator, and to compare among spherical actuators. In this research we developed an evaluation method using a torque map, and realized a torque evaluation at a given position. In addition, we proposed a method to create a torque map of a real machine using magnetic fluxes, and they showed a good agreement with a computed torque map. Finally, a position sensing method using color maps were developed.
