Modeling of Ironless Permanent Magnet Planar Motor Structures

摘要

The modeling of 6 DOF synchronous permanent magnet planar motors is a complex 3D problem [1],[2],[3]. Finite element models (FEM) are time consuming and existing analytical models do not include end effects [1],[2]. In addition, a standard 3-phase sinusoidal commutation cannot be used since the torques vary depending on the position of the mover w.r.t. the stator [3]. The aim is to develop a model that is fast, includes end-effects and allows performance and controllability analysis without specifying a commutation scheme or control method.
