This book introduces and illustrates modeling, sensing, and control
methods for analyzing, designing, and developing spherical motors. It
systematically presents models for establishing the relationships among
the magnetic fields, position/orientation and force/torque, while also
providing time-efficient solutions to assist researchers and engineers
in studying and developing these motors. In order to take full advantage
of spherical motors' compact structure in practical applications,
sensing and control methods that utilize their magnetic fields and
eliminate the need to install external sensors for feedback are
proposed. Further, the book investigates for the first time spherical
motors' force/torque manipulation capability, and proposes algorithms
enabling the ball-joint-like end-effector for haptic use based on these
motors' hybrid position/force actuation modes. While systematically
presenting approaches to their design, sensing and control, the book
also provides many examples illustrating the implementation issues
readers may encounter.
