Abstract

PURPOSE:To continuously vary the slip frequency pattern of the inverter control device by so correcting the set current value as to be proportional to the primary frequency of a motor between the area for controlling the primary voltage at constant value and the slip frequency of the motor and the voltage controllable area. CONSTITUTION:The frequency F3 is increased or decreased in accordance with the magnitude of the primary current IM of the actual motor by the set value Im of the current pattern in a slip frequency correcting unit 72 between the area A for controlling the primary voltage VM and the slip frequency F3 of the motor and the area C of sereis winding characteristics controllable with voltage, and a correction signal is produced to retain the output signal thereat when both becomes coincident. This signal and the slip frequency signal are added by a calculator 73. The unit 72 controls the current pattern under Im proportional FM(primary frequency) resulting in the relationship of F3proportional (FM)2. In this manner it can continuously vary the slip frequency pattern without step in the boundary between the regions.
