The phase estimator estimates a phase of stator interlinkage magnetic flux of an electric motor based on a current flowing through the electric motor, a voltage command of a drive voltage applied to the electric motor, and a winding resistance value of the electric motor. The voltage controller acquires a first voltage vector component in a direction in which the stator interlinkage magnetic flux acts and a second voltage vector component in a direction which is orthogonal to the direction in which the stator interlinkage magnetic flux acts for the voltage command of the drive voltage, and sets the voltage command of the drive voltage based on the first voltage vector component and the second voltage vector component."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Driving device, driving system, and method of driving electric motor","description":"A driving device of one embodiment includes a phase estimator and a voltage controller.
