Design, 3D FEM Simulation and Prototyping of a Permanent Magnet Spherical Motor

In recent years, large tilt angles, uniform magnetic flux distributions, strong forces, and large torques for motors have increasingly become important for robotics, biomedical, and automotive applications that have multi-degrees of freedom (MDOFs) motion. Generally, one-degree of-freedom motors are...

Generally, one-degree of-freedom motors are applied in MDOF motion. These situations cause the systems to have very complex and large structures.
