A high-efficiency brushless ring motor developed by ThinGap Corporation of Ventura, California based on its patented electromotive coil technology promises to reduce energy consumption, allowing such small Unmanned Vehicles (UV), light enough to be carried by a man into reconnaissance or combat...

The standard fan supplied with the amplifiers is a 12V brushless DC motor fan. Like all switching circuits the brushless motor commutation generates electrical noise. If care is not taken in how the fan is connected to the amplifier circuit some of that electrical noise may appear at the output...

...and its ability to. develop pressure will vary. Therefore, when the density of the gas stream is other than the standard .075 lb./ft^3, correction factors must be applied to the catalog ratings in order to select the correct fan, motor, and drive....

...on or completely off. This efficient control methodology affords a very wide speed control range (typically 10% to 100% of full speed) because the fan motor is exposed to its full-rated voltage during the active portion of the PWM cycle. PWM control works with standard, two-wire Brushless DC (BDC) fans...

...unit. will save energy. Indeed, as fan speed is reduced, the motor power reduces by a cube relationship. For. example, a 20 percent reduction in air volume results in an approximate 50 percent power reduction. of the fan motor. But that is only part of the story. This technical note demonstrates...

Horsepower (Not motor horsepower). The formula is given here to demonstrate the fact that the tip speed of the blades is by far the strongest indicator of the noise a fan will produce. To select a low noise fan, therefore, it is most effective to reduce the tip speed by lowering the RPM which can be done...
