Summary:To provide a control device, and a control method which can enhance speed trackability of an electric motor.SOLUTION: A control device supplies power to an electric motor. The control device comprises a control unit. Current restriction of drive current of the electric motor is set to size that depends on speed of the electric motor. The control unit controls a power converter to restrict the drive current of the electric motor to a current restriction value corresponding up to the speed of the electric motor.SELECTED DRAWING: Figure 1 【課題】電動機の速度追従性を高めることができる制御装置、及び制御方法を提供する。【解決手段】制御装置は、電動機に電力を供給する。制御装置は制御部を備える。電動機の駆動電流の電流制限が、前記電動機の速度に依存する大きさに設定されている。制御部は、前記電動機の駆動電流を前記電動機の速度に対応する前記電流制限値までに制限するように電力変換器を制御する。【選択図】図１
