The following describes the content of this system. key words: energy saving,hydraulic power steering, brushless motor 1. Introduction From a viewpoint of recent global e
3、cological problems, an improvement of fuel consumption and exhaust gas regulations such as the Japanese Automobile NOx law have been coming to be world wide important issues. Regulations and taxations that each country tends to impose for environmental protection are enumerated as follows Europe:Int

5、l engine, a hydraulic power steering (called hereafter NPS) of which the power source is an engine-driven hydraulic pump is generally mounted. In this power steering system, a hydraulic pump as mentioned above is rotated in proportion with a revolution speed of engine and runs at high revolution spe

It is said that an energy consumed by such power steering system represents approximately 3% of all the vehicle fue
