April 17,2024, according to the announcement of the State Intellectual Property Office, Gree Electric Appliances, Zhuhai obtained a named “motor braking method, washing machine, computer readable storage medium”, authorization notice number CN113726257B, the application date is September 2021.

The patent summary shows that the present invention discloses a motor braking method, a washing machine, and a computer-readable storage medium. The motor braking method includes: acquiring the voltage deviation value of the motor based on the motor, taking of the voltage deviation value as the input of the PI regulator; and controlling the motor with the corresponding electrical parameters based on the output of the PI regulator until the motor is stopped. The present invention makes the rotation speed of the motor drop smoothly, which can shorten the braking time of the motor and ensure the stability of the motor operation.
