Calculating parameters of frequency-controlled linear asynchronous motors with the composed secondary element

A technique is considered for calculating parameters of the equivalent circuit and electromagnetic forces from each layer of a linear asynchronous motor with the composed rotor. In a mathematical model, there is used the method of secondary element partition by several layers with allowance for nonlinear magnetic characteristic of the ferromagnetic layer. The calculation results are presented on parameters and forces of a linear motor for two values of electric power supply voltage and frequency.
