To provide an operation control system and an air conditioner, and operation control method, and an operation control program capable of improving operation stability.SOLUTION: An operation control system (control device 10) includes a field-weakening control determination part for determining whether field-weakening control is being performed for a three-phase AC motor, and an execution part for performing partial two-phase energization control if the field-weakening control is determined as not performed, the partial two-phase energization control being a control in sine-wave voltage command corresponding to each phase generated based on a speed command of the three-phase AC motor, assuming that a mask period is a predetermined angle range including an electric angle when the amplitude of the voltage command becomes zero, for halting pulse generation during the mask period when a PWM signal is generated based on the voltage command.SELECTED DRAWING: Figure 2 【課題】運転の安定性を向上することのできる運転制御システム及び空気調和機、並びに運転制御方法、並びに運転制御プログラムを提供する。【解決手段】運転制御システム（制御装置１０）は、３相交流モータに対して弱め界磁制御を実施していないか否かを判定する弱め界磁判定部と、弱め界磁制御を行っていないと判定された場合に部分２相通電制御を実行する実行部と、を備え、部分２相通電制御は、３相交流モータの速度指令に基づいて生成された各相に対応する正弦波の電圧指令において、電圧指令の振幅が零となる電気角を含む所定の角度範囲をマスク期間として、電圧指令に基づいてＰＷＭ信号を生成する場合にマスク期間の間パルスの発生を停止する制御である。【選択図】図２
