Abstract:
A fan motor braking apparatus and a method of controlling the same provide a braking protection before the fan motor revolves. The fan motor braking apparatus includes a conversion circuit, a braking enable circuit, a braking release circuit, and a fan motor startup circuit. The conversion circuit has a plurality of power switch elements electrically connected to the fan motor. The braking enable circuit is connected to the conversion circuit and the braking release circuit is connected to the braking enable circuit. The fan motor startup circuit receives an external DC voltage. The braking enable circuit generates a braking control signal to turn on the power switch elements when the braking enable circuit receives the external DC voltage, thus braking the fan motor.
