A double-layer Halbach array magnetic roller model is proposed,which has stronger external magnetic field and better sinusoidal magnetic field.Through the magnetic scalar potential method,the mathematical model of the magnetic field distribution law of the magnetic roller is established,and the mathematical expressions of radial and circumferential magnetic flux density are obtained.The magnetic field of the magnetic roller is simulated and analyzed by using the finite element simulation tool,and the distribution law of the external magnetic field of the magnetic roller is obtained.Through the simulation tool,the structural parameters of the magnetic roller are optimized.
