To provide a motor control device in which, when voltage is low, reduction in output torque can be suppressed.SOLUTION: In an integrated valve apparatus including a single motor, and a valve body part having a shaft portion which moves in the axial direction thereof on the basis of driving of the motor and a plurality of valves which are opened/closed by being engaged, in the axial direction, with the shaft portion, the motor control device includes a control unit that controls the motor. The motor has a winding wire wound therearound on the basis of a normal voltage value which is required to open/close the plurality of valves. When a power source voltage becomes below a first specified value lower than the normal voltage value, the control unit makes the rotational speed of the motor lower than that obtained at the normal voltage value.SELECTED DRAWING: Figure 7
【課題】低電圧時における出力トルクの低下を抑制できるモータ制御装置を提供する。【解決手段】モータ制御装置は、単一のモータと、前記モータの駆動に基づいて自身の軸方向に移動する軸部及び該軸部との軸方向への係合により開閉される複数の弁を有する弁本体部と、を備えた統合弁装置の内の前記モータを制御する制御部を有するモータ制御装置であって、前記モータは、前記複数の弁の開閉時に必要となる通常電圧値に基づいて巻線が巻回されるものであり、前記制御部は、電源電圧が前記通常電圧値よりも低い第1の規定値を下回った際に、前記通常電圧値における前記モータの回転数よりも低下させる。【選択図】図7
