したことを特徴とする回転機械の容量制御装置。One first AC motor 1 driven by an inverter 3 and one or more second AC motors driven by a commercial AC power source.
A plurality of rotating machines each individually driven by the AC motor 2 are provided in combination with a single system load, so that the capacities of the respective rotating machines are approximately equal, and the second AC motor 2
compares the capacity control signal S1 extracted as a voltage with a value proportional to the change in the single system load and the reference setting voltage signal S2 corresponding to the load when the first AC motor 1 is operated at the rated output. In the load increase process, the capacity control signal S1 is operated under the condition that the value is equal to or higher than the reference setting voltage signal 82, and in the load decrease process, the capacity control signal S1 is
Start/stop control is performed to stop the first AC motor 1 under the condition that □ is equal to or less than the voltage signal 83, which is a value slightly lower than the reference setting voltage signal S2, while the first AC motor 1 is stopped when the second AC motor 2 is stopped. When the second AC motor 2 is operating, the second AC motor 2 is operated by the inverter 3 which emits a frequency proportional to the capacity control signal S□, and when the second AC motor 2 is operating, the second AC motor 2 is The inverter 3 operates by emitting a frequency proportional to the value obtained by subtracting the voltage signal S4 corresponding to the load when the inverter 3 is operated at the rated output, thereby performing stepless capacity control. Machine capacity control device.
