の定出力制御装置。 A powder mixer includes a drive motor 1 and a stirring blade 5 driven by the drive motor 1, and the stirring blade 5 is disposed in a tank 6, and the drive motor 1 is connected to an inverter controller 3. a rotation speed detector 7 that is connected to an AC power source through the drive motor 1 and detects the rotation speed of the drive motor 1; and a voltage converter 8 that converts the measured frequency corresponding to the measured rotation speed detected by the detector 7 into a voltage. Then, the slip frequency outputted from the inverter controller 3 and obtained by subtracting the measured frequency corresponding to the measured rotational speed detected by the rotational speed detector 7 from the synchronous frequency for driving the drive motor 1 is within a certain range. A constant output control device for a powder/granular material and fluid mixer, characterized in that the device is equipped with a slip frequency corrector 9 for presetting the relationship between frequency and voltage and controlling the output frequency of the inverter controller 3. .
