Design and Simulation of Novel 3-DOF Spherical Voice Coil Motor

چکیده
Multi-DOF motion is realized in the eyes and joints of robots mostly through combination multiple one-degree-of-freedom (1-DOF) motors. However, this results reduced efficiency, a large volume, response speed, inaccurate positioning. To solve these problems, study proposes novel 3-DOF spherical voice coil motor (VCM). In VCM, 16 coils radially oriented ring magnet are used to generate Lorentz force achieve motion. particular, for Z-axis rotation sandwiched between X- Y-axis rotation. Furthermore, proposed VCM can 360° about Z-axis. The commercial software ANSYS was design verify performance VCM. Simulation indicate that affords improved power efficiency because only suitable coils, rather than all needs be powered on. demonstrate feasibility

INSTRUCTIONS Precision nano-positioning techniques have become very important for biomedical science, optics and microscopy. PZT and flexure compliant mechanisms are widely used in these various fields and applications within these fields. Compliant mechanisms are flexible structures, which can generate the desired motions by undergoing elastic deformation instead of through rigid linkage/joint...
متن کاملStatic Balancing of Spherical 3-DOF Parallel Mechanisms and Manipulators
The static balancing of spherical three-degree-of-freedom (DoF) parallel mechanisms and manipulators is addressed in this paper. Static balancing is defined here as the set of conditions on mechanism dimensional and inertial parameters which, when satisfied, ensure that the weight of the links does not produce any torque (or force) at the actuators for any configuration of the mechanism, under ...
