Abstract
We have developed a coupled system simulator that can be used in a model-based development method to improve the effectiveness of an airscrew compressor. A feature of this simulator is that it consists of models of an electrical and a mechanical system, and it can be investigated by using coupled analysis. The mechanical model consists of a compressor and a power transfer mechanism. The compressor model is capable of calculation covering all operation speeds combining the load torque of regular operation from theoretical calculation of gas compression, and the load torque at the time of starting from the model created by the data obtained from the experiment. The electric model consists of a power supply, an inverter, and a brushless DC motor. Since the motor model can directly use the magnetic field analysis result, motor evaluations can be done quickly. We set out an outline of the modeling, provide a detailed model of the compressor, and explain the result of our calculation.
