| 摘要 | Vacuum cleaners and methods of controlling a motor driven by a battery source in a vacuum cleaner. The vacuum cleaner has a motor, a battery source for providing power to the motor, a voltage measuring unit for measuring a voltage over the motor, and a current measuring unit for measuring a current flowing through the motor. Further, the vacuum cleaner comprises a control unit for controlling, based on the measured voltage and/or the measured current, the power provided to the motor from the battery source to attain a target motor power value during a specified time period running from start-up of the motor, and to gradually decrease the power provided to the motor after the time period ends. | ||

| 主权项 | 1. A method of controlling a motor driven by a battery source in a vacuum cleaner, the method comprising: measuring at least one of a motor voltage over the motor and a motor current flowing through the motor; and controlling, based on the measured motor voltage and/or the measured motor current, the power provided to the motor from the battery source to attain a target motor power value that is substantially constant during a specified time period running from start-up of the motor and, when the specified time period has expired, controlling the power provided to the motor to gradually decrease with decreasing battery source voltage until the motor is powered off. | ||
