This paper proposes an ironless permanent magnet linear synchronous motor (ILPMLSM) with a novel Halbach array. The magnetic flux density distribution of the Halbach array is solved analytically by using the equivalent magnetization intensity method. The expressions of no-load back-EMF and electromagnetic thrust are obtained. All of the results are verified by finite element method and they are coincide very well.
