Zusammenfassung: | To provide a motor controller which can perform control suitable in instantaneous voltage drop by detecting generation of the instantaneous voltage drop.SOLUTION: The motor controller has: a rectification circuit which rectifies AC power supplied from an AC power source; a smoothing circuit which smooths output of the rectification circuit; a motor drive part which drives a motor by applying the output of the smoothing circuit to the motor; a voltage detection part which detects voltage of the output of the smoothing circuit; and a control part which controls voltage applied to the motor by the motor drive part. The control part determines a voltage reduction state of the AC power source based on the voltage detected by the voltage detection part, and applies a pattern in speed reduction in order to control the voltage applied to the motor by the motor drive part when determining the fact of being the voltage reduction state.SELECTED DRAWING: Figure 1
【課題】瞬低発生を検出することにより瞬低時に適した制御を実行可能なモータ制御装置を提供することである。【解決手段】モータ制御装置であって、交流電源から供給された交流電力を整流する整流回路と、前記整流回路の出力を平滑する平滑回路と、前記平滑回路の出力をモータに印加することでモータを駆動するモータ駆動部と、前記平滑回路の出力の電圧を検出する電圧検出部と、前記モータ駆動部が前記モータに印加する電圧を制御する制御部と、を有し、前記制御部は、前記電圧検出部で検出した電圧に基づき、前記交流電源の電圧低下状態を判定し、前記電圧低下状態であると判定した場合に、前記モータ駆動部が前記モータに印加する電圧の制御に、減速時パターンを適用する。【選択図】図1 |
