A Study on the Parameters and Characteristics of Induction Motor driven by Inverter

인버터로 구동되는 유도전동기의 정수 및 특성에 관한 연구

This paper presents the calculation method for the equivalent-circuit parameters and torque characteristics of squirrel-cage induction motors. The measurement of motor parameters were calculated by the stator resistance test, the blocked rotor test and no load test to T type equivalent-circuit. Especially, this paper describes the test results obtained by using hall sensor and strain gauge for the current and torque characteristics of induction motors. Three-phase squirrel-cage induction motor which has 1[hp] was used to the test and the parameters obtained by the test were compared with the maker parameters.
