Abstract
A linear induction motor (LIM) is suitable for use in trains; the motor can be used in both wheel-suspended and contact-less types such as Linear Metro and HSST trains in Japan. The LIM has the end winding as well as asymmetrical winding. The end-effect is a major problem in the LIM, and it makes the analysis, design, and control of motors difficult. In this paper, the combination method of numerical analysis and equivalent circuit of the LIM is described in order to design a high-performance controller of the LIM includeing the end effect. A sample basic field-oriented control scheme that is based on the plant model is applied to the LIM in order to check the control performance; the theory of rotary induction motor is used for the verification.
