전류 위상각 제어에 의한 단상유도전동기의 에너지 절감에 관한 연구 = A Study on the Energy Saving SPIM Using Phase Angle Control of Current

다국어 초록 (Multilingual Abstract)

For the SPIM is can' t generate rotating flux itself, an additional starting system should be installed on the SPIM. There are several methods embody the starting system. Among the methods, capacitor start method is composed of a starting condenser and centrifugal. But the centrifugal switch and the starting condenser have some problems of the starting failure, the breaking under the worse condition and it brings about the short life of the motor.
Nowadays, users demand higher efficiency, reliability, miniaturization and noise immunity than the conventional motor. This paper describes a simple but effective method for energy saving of ac motors having a widely variable load. The proposed method is based on an optimal efficiency control which is operated by voltage-current pattern such as to maintain the maximum efficiency on the efficiency-output characteristics of the motor, in voltage control with TRIAC. In this paper, author presents the experimental results of the SPIM under phase angle controlling of current of main and auxiliary winding by using a one-chip microcontroller. Experiments are focused on a capacitor starting single phase induction motor, the optimal energy savingare proved by the proposed method.
