  • The changes of the main body temperature of a I tube 2 chamber bent silkworm type dyeing machine and the reduction of energy consumption of the dyeing machine by the energy saving design are reported. This dyeing machine was developed for the purpose of the energy saving and high efficiency. In this study, the changes of the main body temperature of the 1 tube 2 chamber bent silkworm type dyeing machine were studied experimentally. Especially the effect of the blower motor electric current and the main body pressure at various blower frequencies were studied experimentally. In the experimental data for the changes of main body temperature, it was shown that the main body temperature increased as the blower motor electric current and the main body pressure increased.

  • The driving characteristics of the 1 tube 2 chamber bent silkworm type dyeing machine are reported. This dyeing machine is a newly developed energy saving machine. In this study, the driving characteristics of the 1 tube 2 chamber bent silkworm type dyeing machine are examined. Specially the relationship between main body pressure and the electric current of the blower motor, the relationship between main body pressure and the air pressure of the blower nozzle, the effect of the air pressure of the blower on the running speed of the fabric, and the effect of main body temperature were discussed experimentally. Through the experimental data, the following results were obtained. 1. Blower motor electric current and blower nozzle air pressure increased as main body pressure increased due to the temperature increase of the main body. 2. The running speed of the fabric increased as blower nozzle air pressure increased. The difference in running speed between winch reel driving and no winch reel driving at a blower frequency of 60Hz was higher than that of 70Hz. 3. The electric current of the blower rioter and blower nozzle air pressure increased rapidly at the initial state. As the experimental time passed, the main body pressure increased slowly. as the main body temperature increased.

  • 송풍기를 이용한 제품으로는 핸드드라이기, 자동세차기, 건조기, 청소기등이 있다. 이러한 전동기의 특징은 순간에 강한 바람이 나오도록 구조, 제어 알고리즘이 필요하다. 종래의 여자방식에 따른 전동기는 직권식, 분권식, 복권식, 영구자석식이 있다. 이러한 전동기는 고속 회전 시 기동전류가 크고 회전수가 불규칙한 단점이 있다. 이를 개선하고자 고속BLDC 전동기 제어에 관한 연구로 구동회로 설계, 센서리스 제어 알고리즘, 시뮬레이션, 실험 등을 통해 800W급 고속BLDC 모터 제어와 회로 설계하였고, 95% 이상 고효율을 제어기의 운전성능 평가 방법, 시제품 실험 및 검증을 연구하였다.
