Abstract
A DC electric fan receiving a first direct current voltage is provided. The DC electric fan includes a motor, a fan blade, a voltage converting device and a motor controller. The motor is directly driven by the first direct current voltage. The fan blade is connected to the motor and rotated by the driving of the motor. The voltage converting device receives and converts the first direct current voltages to a second direct current voltage, wherein the magnitude of the first direct current voltages is larger than the magnitude of the second direct current voltage. The motor controller receives the second direct current voltages to control a rotation direction of the motor, wherein the motor controller is not powered by the first direct current voltage and the first direct current voltage is a fixed direct current voltage.
