To provide a motor control device capable of shortening a valve switching time while securing a necessary torque.SOLUTION: An integrated valve device 24 is configured to switch a refrigerant flow in a refrigeration cycle device between a heating mode and a cooling mode and includes: a single motor 26; and a valve body 25 having first to third valves 31 to 33 that are opened and closed on the basis of a driving force of the motor 26. An integrated valve ECU 27 which controls a drive of the motor 26 includes a drive current control unit 27a for changing a rotation speed of the motor 26 at a timing on the basis of opening and closing of the first valve 31 (first valve seat 52).SELECTED DRAWING: Figure 2
【課題】必要トルクを確保しつつも弁の切り替え時間を短縮可能としたモータ制御装置を提供する。【解決手段】統合弁装置24は、冷凍サイクル装置における冷媒の流れを暖房モードと冷房モードとで切り替えるものであって、単一のモータ26と、該モータ26の駆動力に基づいて開閉される第1〜第3弁31〜33を有する弁本体部25とを備える。そして、モータ26の駆動を制御する統合弁ECU27は、第1弁31(第1弁座52)の開閉に基づくタイミングでモータ26の回転数を変える駆動電流制御部27aを備える。【選択図】図2
