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...
The magnetic fields due to different planar Halbach permanent magnet (PM) array, including the 4 piece square array, stretched 8 piece square array and trapezoid array, are studied by analytic calculation method and FEM. On this basis, the magnetic forces over the magnet weight per array unit area are obtained. Then comparisons of above results indicate that the trapezoid array can provide the maximum...
