In this paper, a maglev transportation system with a Linear Induction Motor (LIM) is introduced. It is proposed that two different frequency components are used to achieve the simultaneous and independent control of the thrust and attractive force of LIM. One of the frequency components is synchronous with the motor speed (fm). The other frequency is drive frequency (fd) that generates the thrust...
In this paper, it is proposed to use a matrix converter for linear induction motor (LIM) drives. A matrix converter is a direct AC-AC converter. It has the potential to regenerate power and to connect directly across the AC power line, thus it is possible to improve the efficiency in the entire system of LIMs drive. In this experiments, the operating characteristics of the matrix converter were examined...
In this paper, a novel maglev transportation system of the Linear Induction Motor (LIM) is introduced. It is proposed that two different frequency components are used to achieve the simultaneous and independent thrust and attractive force control of the LIM. One of the frequency components is synchronous with motor (fm) that is used to control the levitation of LIM. The other frequency is drive frequency...
Linear motors have many applications because of their unique characteristic which are different from rotary machines. In particular, Linear Induction Motors (LIMs) have a simple and strong structure, a flexible mechanism, and so on. The most popular application of LIMs is in transportation systems. It is important to investigate the dynamic characteristics of LIMs in order for them to be successfully...
