There are turbo air compressor as a essential equipment on the industrial spot. And this type of compressor has required a high ratio gearbox and a conventional induction motor driving system so that it needs a high speed rotation of impeller in structure. This mechanical system have results of increased moment of inertia and mechanical friction loss. The recent studies of modern turbo compressor have been applied to developing super high speed BLDC motor and driver system which could remove gearbox that make its size small and mechanical friction loss minimum. To accomodate this tendency, we tried to develope a super high speed motor drive system for the 150Hp, 70,000rpm direct drive Turbo compressor using DSP(Digital Signal Processor) and SVPWM(Space Vector Modulation PWM) technique. The results of this specific application show that super high speed driver and controller could be implemented well with digital electronics.

Turbo compressor needs high speed rotation of impeller in structure, high rated gearbox and conventional induction motor. This mechanical system increased the moment of inertia and mechanical friction loss. Resently the study of turbo compressor applied super high speed motor and drive, removing gearbox made its size small and mechanical friction loss minimum. In this study we tried to simulate variable super high speed motor deriver and direct drive turbo compressor air pressure control. The result of study is applied to a 70,000rpm/150Hp direct turbo compressor and makes it goods.
