To improve the end-effect influence, which is a main reason of influence on the characteristic of linear motor, wavelet analysis is used in study the end-effect of linear motor in this paper. Traditional analysis method is based on the Fourier transform, but it analyzes the non-stable signal will be usually lost some messages. Because of the time frequency location characteristic of wavelet transform. Then wavelet transform research on end-effect analysis of linear motor is proposed. This paper compares the Fourier transform with wavelet transform to analyze the end-effect, the results are shown that the wavelet transform is further suitable for improve the end-effect influence of linear motor. Then it makes the control system of linear motor have good performances.

The derivation of the equivalent circuit for a single-sided linear induction motor (S LIM) is not straightforward, particularly if it includes longitudinal end effects from the cut-open primary magnetic path, transversal edge effects from the differing widths between the primary lamination and secondary sheet, and half filled primary slots. This paper proposes an improved series equivalent circuit for this machine. The longitudinal end effects are estimated using three different impedances representing the normal, forwards and backwards flux density waves in the air-gap, whose two boundary conditions are deduced by introducing the conception of magnetic barrier surface. The transversal edge effects are accounted by correction coefficient t K and an air-gap flux density correction coefficient b K. Using the series circuit, the performance of the S LIM was assessed in a similar manner to a rotating induction machine. A 4 kW S LIM prototype was tested which validated the simulation technique.

“…In his model, the equivalent circuits for three phases were the same, and therefore, this model is unable to show asymmetry in three-phase input currents and also braking force as an end effect result. Some models were based on electromagnetic field in the air gap, developed by Fourier series transform [7,8]. Stepping time method is used to determine these models, which make the control process complicated.…”

SUMMARYIn this paper, a new dynamic model for disk-type linear induction machines (LIMs) is introduced. In this model, the rotor is divided into two regions where regions 1 and 2 are under and out of stator, respectively. In the second region, the rotor is not magnetically coupled with magnetic circuit of the stator, whereas magnetic circuit of region 1 of the rotor is magnetically coupled with magnetic circuit of the stator. A winding function approach is developed and used for calculation of new model inductances. Also, a prototype disk-type LIM is used to produce the experimental results and show the validity of the introduced model. The results showed that the new model can represent the end effect of LIM, dynamically.
