Impact on thrust force in construction parameters of slotless permanent magnet linear synchronous motor

Divided layers model and physical model of slotless permanent magnet linear synchronous motor (PMLSM) are built. Magnetic vector potential is regarded as variables to gain solution of excitation magnetic field and armature response magnetic field. Through two-dimensional analytical method, different construction parameters are analyzed to affect thrust force. The finite element method (FEM) is confirmed agreement with analytical method, indicating the validity of analytical method and the reasonable of method.
