英文摘要：

This paper explained the structure features and operation principle of the deep-slot single phase linear induction motor, and proposed the analysis model based on the field-circuit combined method. It used the finite element method （FEM） to analyze the magnetic distribution within the effective width of primary lamination and the circuit method to simulate the end of primary winding. This model included primaries of multi-motors and secondary of one motor, which can calculate both the steady performances such as the airgap magnetic field, thrust, capacitor voltage, secondary eddy-current power, etc at the motor locked condition and the dynamic performance such as current, velocity, thrust, etc at the motor starting condition. In addition, the effect of the structure parameter and capacitor capacity on motor performance can be investigated. The analysis results show that the starting current is low and the capacitor capacity is much high. Due to the experimental results of the prototype were coincidence with the analysis results, the effectiveness of this proposed model was proved.
