□ Outline of Technology
- A technique for controlling a flow rate control valve by setting each limit value depending on stages according to angular speed components of a drive voltage that is applied during angular speed control over the DC motor and using a reference value of controlling target.
- The DC motor is rotated at an intended angular speed so that a control valve to which the DC motor is mounted is controlled, thereby enabling precise control of a flow rate.
