Abstract

Based on vector magnetic potential and scalar magnetic potential, the theoretical model of bilateral permanent magnet synchronous linear motor is established, and the analytical expression of the magnetic field in the target region is given. Based on the expression, the variation of magnetic field with wavelength, air gap and thickness of permanent magnetic material is analyzed, and the reasonable range of wavelength design value is pointed out. The formula of electromagnetic force is derived, and the expression of electromagnetic force produced by permanent magnetic material per unit weight is obtained.
