Abstract The 6-slot, 7-pole single-sided flat-plate permanent magnet synchronous linear motor (PMLSM) generates thrust fluctuations during operation, resulting in poor machining accuracy. This paper proposes an optimization method combining magnetic pole misalignment and V-shaped magnetic poles to improve its performance. Firstly, the end magnetic field is analyzed by the Huck transform method to obtain the analytical expression of the total thrust fluctuation caused by the end effect. Then the Fourier coefficients in the analytical formula are analyzed, and the main harmonic order of thrust fluctuation caused by the end effect is obtained. Through the finite element simulation of a variety of permanent magnet structures, the method of V-shaped three segment dislocation pole is obtained from the force characteristics. When the phase difference between the two poles and the middle pole is 90 degrees, the thrust fluctuation can be effectively reduced. Finally, a prototype was made based on this method. The finite element results and prototype experiments verify the feasibility of this method, which provides a guidance for the optimal design of single-sided flat PMLSM.

Key words： V-shaped three-stage magnetic pole dislocation Huck transform method cogging magnetic resistance end normal force fluctuation permanent magnet synchronous linear motor finite element simulation
