【Abstract】 Considering the specifications of the motor in practical situation,some criteria and calculation formulas applied to the design of the PMLSM were proposed,in which determination of electromagnetic load and main sizes,designing of the PM mover and the primary and the winding as well,calculation of parameters and the back EFM etc.were included.Some design criteria were concluded after having much discussion on the field in air-gap and specifications of the motor affected by the motor main sizes,based on a 2-D field analytical solution and/or relative results obtained by FEM.The results calculated by FEM and measured by experiments show that the analytical formulas are suitable.更多还原
