Abstract
A fan motor braking apparatus includes a fan motor, a conversion circuit and a motor driver circuit. The conversion circuit is respectively and electrically connected to the fan motor and the motor driver circuit. The conversion circuit includes bridge structures. After the fan motor starts operating, the motor driver circuit receives at least one fan status signal and determines whether the fan motor braking apparatus enters a braking status or not according to the at least one fan status signal. When the fan motor braking apparatus enters the braking status, the motor driver circuit outputs a braking control signal to the conversion circuit so that the bridge structures of the conversion circuit generate a brake effect on fan motor, wherein the at least one fan status signal includes an external speed-control signal and a transition voltage signal of the fan motor.
