Document Type and Number:
Japanese Patent JP2022178156
Kind Code:
A
Abstract:
To provide a motor driving control system capable of continuously driving a motor at minimum necessary power supply capacity even when emergency such as commercial power source loss occurs.SOLUTION: A motor driving control system according to one embodiment comprises a plurality of first inverters for independently driving a plurality of motors by a vector control system, using first power supplied from a commercial power supply; and a second inverter for collectively driving the plurality of motors by a V/F control system during power supply loss by which no first power can be supplied from the commercial power supply, using second power supplied from a power generator.SELECTED DRAWING: Figure 1
