In this paper, different types of planar permanent magnet array are studied by FEM, calculation and experiment. Then a variety of characteristic graphs are presented, conclusions obtained by analyzing these graphs will enable us to learn the arrays comprehensively and systematically. Starting with the standard Halbach array, then the effects of magnets size, Segment Numbers Per Pole, Magnet Shapes...
In this paper, an analytical approach is presented to calculate the magnetic force between the mover and the stator of an electromagnetic planar actuator. The key is to use the coenergy method to calculate the force, in such a way that the stator current can be predicted properly to offer the accurate orientation and location for the real-time control of the high-precision planar actuator. The proposed...
