摘要： A drive circuit of a fan motor is provided. In an embodiment of the drive circuit, a first PWM comparator compares a temperature detection voltage with a cyclic voltage, and outputs a first PWM signal. A second PWM comparator compares a minimum frequency setting voltage indicating a minimum frequency of the fan motor, with the cyclic voltage, and outputs a second PWM signal.

The drive circuit includes a first logic gate which generates a logical sum of the first PWM signal and the second PWM signal, and a second logic gate which generates a logical product of the first PWM signal and an inverted signal of the second PWM signal. The drive circuit switches drive mode based on the first logic gate and the second logic gate.

摘要： A wire harness for a holding a plurality of wires in a cabinet having a front section and a rear section is disclosed, wherein the front section includes a first inner wall and the rear section includes a second inner wall. The harness includes a first vertical flange extending downward from the first inner wall, wherein the flange includes a slit extending through a first end of the flange and terminating before a second end of the flange to form upper and lower rib elements. Further, the slit forms an opening in the first end for receiving the wires into the slit. The harness further includes a shoulder element having a second vertical flange and a horizontal flange, wherein the second vertical flange extends downward from the second inner wall and is separated from the first vertical flange by an offset distance. Further, the horizontal flange is positioned adjacent the lower rib and separated therefrom by a distance which is less than a thickness of each of the wires, thereby capturing at least one of the wires which is displaced from the slit between the horizontal flange and the first and second inner walls.
