Patent number: 11456689Abstract: According to one embodiment, a driving device includes a voltage controller, a parameter setter, and a phase adjuster. The voltage controller causes an electric power converter to apply a drive voltage to the electric motor, the electric power converter converting input electric power to A/C electric power having desired voltage and frequency and supplying the converted electric power to an electric motor. The parameter setter sets at least one of a rotation speed of the electric motor and a parameter related to the rotation speed as speed information. The phase adjuster adjusts a phase of the drive voltage in such a manner that an index calculated based on a current flowing in the electric motor and the speed information set in the parameter setter becomes smaller.Type: GrantFiled: December 23, 2019Date of Patent: September 27, 2022Assignees: KABUSHIKI KAISHA TOSHIBA, Toshiba Electronic Devices & Storage CorporationInventors: Takashi Takagi, Toshimitsu Aizawa, Shen Wang
