Abstract

In this paper, the system equation for the balanced two-phase induction motor is derived and the characteristics for speed control is also analyzed in the region of constant torque and constant power. The modified vector control theory is applied to two-phase motor drive system. The speed of two-phase motor drive can be controlled precisely by the modified indirect vector control theory. The modified vector control theory is simpler comparing to the conventional vector control because of the simpler axis transformation. The computer simulations and the experimental results presented to confirm the vector control for two-phase inverter fed two phase induction motor system.

본 논문에서는 평형 2상유도전동기에 대한 시스템 방정식을 유도하고 해석하였으며, 동기좌표계에서 평형 2상유도전동기의 속도제어 특성을 분석하였다. 3상 교류 전동기의 속도제어에 범용적으로 적용하는 벡터제어이론을 "2상 인버터 구동 2상 유도전동기 시스템"에 수정하여 적용하였으며, 이 때 2상 유도전동기 시스템은 수정된 간접 벡터제어이론에 의해 속도 제어하였다. 2상 유도기의 벡터제어의 특성과 근사함을 보여주기 위해 제안 시스템을 시뮬레이션하였다. 최종적으로 실험을 통해서 제안 시스템이 벡터제어에 확실히 적응하는 것을 확인하였다.
