High-speed Motor Driven by Fluid Power

抄録

The present paper reports a high-speed motor driven by fluid power. The torque produced by a flow supplied to the motor generates high-speed rotational motion. Bend channels of small diameter in the motor's rotor produce the torque. The fl ow in the bend channels generates a large change in angular momentum to produce the torque. The advantages of the highspeed motor are a simple structure and the absence of large frictional forces acting on the moving elements of the motor. These advantages allow the motor to be driven by not only air flow or oil flow, but also water flow. In the present paper, a mathematical model is first derived, and then two design procedures, a power-based design procedure and an efficiencybased design procedure, are presented. Finally, the characteristics of the motor designed using the power-based design procedure were measured experimentally and then compared to results obtained via simulation.
