To provide a motor control device capable of driving a motor with respect to heavy load while suppressing heat generation.SOLUTION: An integrated valve device 24 switches flow of a refrigerant in a refrigeration cycle device between a heating mode and a cooling mode, and includes: a single motor 26; and a valve body part 25 having first to third valves 31 to 33 opened/closed on the basis of driving force of the motor 26. An integrated valve ECU 27 as a motor control device is provided with a current value variable control part 27a variably controlling current value of the drive current to be supplied for the motor 26. The current value variable control part 27a increases current value of the driving current at timing based on opening/closing of the first valve 31 (a first valve seat 52).SELECTED DRAWING: Figure 2
【課題】発熱を抑えつつ、高負荷に対するモータの駆動を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、モータ制御装置としての統合弁ECU27は、モータ26に供給する駆動電流の電流値を可変制御する電流値可変制御部27aを備え、該電流値可変制御部27aは、第1弁31(第1弁座52)の開閉に基づくタイミングで駆動電流の電流値を増加させる。【選択図】図2
