PROBLEM TO BE SOLVED: To provide a motor device capable of performing motor drive and voltage transformation drive between two power supplies together, and capable of performing only motor drive easily.SOLUTION: A control section 70 is configured to be able to adjust a voltage transformation ratio from a second power supply 50 to a first power supply 40, or a voltage transformation ratio from the first power supply 40 to second power supply 50, by adjusting the ratio between a first period when all upper arm side switching elements are turned on and all lower arm side switching elements are turned off, and a second period when all upper arm side switching elements are turned off and all lower arm side switching elements are turned on, and is also configured to be able to switch both a drive mode of performing motor drive and voltage transformation drive, by including first and second periods in one control period of the motor 30 during drive, and a motor drive mode of performing only motor drive, by not including first and second periods in one control period of the motor 30 during drive.SELECTED DRAWING: Figure 1 【課題】電動機駆動と２つの電源間の変圧駆動を一緒に行うことができるとともに電動機駆動のみを容易に行うことができる電動機装置を提供する。【解決手段】制御部７０は、全ての上アーム側スイッチング素子がオンになるとともに全ての下アーム側スイッチング素子がオフになる第１期間と、全ての上アーム側スイッチング素子がオフになるとともに全ての下アーム側スイッチング素子がオンになる第２期間との比率を調整して第２電源５０から第１電源４０への変圧比または第１電源４０から第２電源５０への変圧比を調整可能に構成され、かつ、電動機３０の駆動中の１つの制御周期内に第１期間及び第２期間を含むことで、電動機駆動と変圧駆動を行う両駆動モードと、電動機３０の駆動中の１つの制御周期内に第１期間及び第２期間を含まないことで、電動機駆動のみを行う電動機駆動モードとを制御周期毎に切り替え可能に構成されている。【選択図】図１
