  • Publication number: 20240063739
    Abstract: A control method for a fan, a fan, a household appliance, and a computer-readable storage medium are provided. The fan includes an electric motor. The control method includes: controlling the electric motor to start to operate through a d-axis current command in response to a start command; obtaining an actual speed of the electric motor, and starting timing when the actual speed reaches a first target speed; and decreasing, when the timed duration reaches a first preset duration, a d-axis current corresponding to the d-axis current command until the d-axis current is decreased to 0, and increasing a q-axis current corresponding to a q-axis current command until the q-axis current is increased to a first target current.
