Equivalent Circuit Constants and Characteristics Calculation of LIM by Lock test

구속시험에 의한 선형 유도 전동기의 등가회로 정수 산정 및 특성 계산

The equivalent circuit of linear induction motor is generally expressed as the same that of rotary induction motor. However, it is almost impossible to perform the no-load test for LIM, because it needs a special equipment for synchronous speed. Therefore, a new method is reqnired to calculate the performance of the LIM without the no-load test. In this paper, The new method which does not need no-load test for the chanracteristics analysis of LIM is proposed. The equivalent circuit of LIM is chosen and the method if determining its constants from results of the lock test is discussed. The calculated results were satisfied by compare with experimental and conventional method results.
