Equivalent Circuit Composition of a Linear Induction Motor

선형유도전동기의 등가회로 구성 - LIM의 T형 등가회로 산정을 위한 구속시험 -

The equivalent circuit of LIM is generally composed as the same that of rotary induction motor. However it is very difficult to move the LIM at synchronous velocity for open-secondary circuit test. The resistance representing the core losses in the primary core can not be ignored because the air-gap of LIM is larger than that of rotary induction motor. In this paper, the T-type equivalent circuit of a LIM with the core loss resistance is chosen using static zero slip test and theoritical analysis.
