Abstract
A fan system and a stopping method for the fan system are provided. The fan system is electrically connected to a power supply and receives the power therefrom. The fan system includes an energy storage apparatus, a motor and a start-up device. The energy storage apparatus receives and stores the power. The motor is electrically connected to the energy storage apparatus and receives the power. The driver is coupled between the energy storage apparatus and the motor to form a control path and generates a driving signal to the motor according to received power. The start-up device is coupled between the energy storage apparatus and the motor to form a power path therewith. When no power is provided to the fan system, the energy storage apparatus releases the stored power and the start-up device generates a start-up signal to the motor in accordance with the released power so as to form a short-circuit loop in the motor to stop the motor.
