Design and Analysis of a Novel 2-D Permanent Magnet Array for Planar Actuator

  A novel 2-D permanent magnet array for a planar actuator was proposed,in which the portion between adjacent magnetic poles was divided to four small rectangular solids.Magnetic fields of the permanent magnet array were analyzed systematically by 3D finite element method.The analysis results show that,compared with the well-known Halbach magnet array,the proposed array has higher permanent magnet utilization.Keeping the whole permanent magnet volume constant,the arrays with several improved structures were put forward.The magnetic field analyze results prove that the utilization is best,when the ratio between the height of the magnetic poles magnetized vertically and the height of the portion magnetized horizontally is about 2.
