Honeycomb Halbach Flexible Permanent Magnet Array for Magnetically Levitated Planar Motor
Based on the prototype Halbach planar magnet array (HPMA), a honeycomb Halbach flexible permanent magnet array (HHFA) is proposed in this article. HHFA can effectively optimize the magnetic field distribution, increase the magnetic field strength, and reduce the magnetic field distortion. The magnetic flux density distribution for HHFA was obtained through a numerical analytical approach. The simulation and comparative analysis show that the intensity amplitude of the magnetic field generated by HHFA is 23% higher than that of HPMA, and the periodic distortion rate, amplitude fluctuation of the magnetic field, and harmonic distortion of HHFA are optimized compared with HPMA. The simulation results demonstrate that magnetically levitated planar motor (MLPM) employing HHFA exhibits superior electromagnetic thrust coefficient and electromagnetic force stability compared to MLPM utilizing HPMA.
