In order to meet the requirement of ocean energy power generation, a novel linear rotary permanent magnet machine (LRPMM) is proposed with E-type stator structure and interlaced poles. The adjacent interlaced PM poles in the circumferential direction are staggered half pole pitch in the axial direction. The optimization design of LRPMM is analyzed by analytical calculation method and 3-D finite element method (FEM), and the best optimization variable values are achieved. Compared with the results of the traditional topology analyzed by 3-D FEM, the electromagnetic characteristics are increased and the amplitudes of the cogging torque and detent force are reduced. An energy storage system of LRPMM is built, which can improve the effective utilization of wave energy and tidal energy.
