• Fan Design

The following discussion describes the basic considerations in efficient axial flow fan design and illustrates features that will assist the reader in recognizing well-designed units. One of the most important requirements of a fan wheel is that is must impart to the air stream a uniform velocity

• Redundant Fan Systems Using the TC647 Fan Manager

Certain applications, such as file servers, require redundant cooling fans to ensure uninterrupted system service, even with cooling fan malfunctions present. Typically, such systems have a primary fan to cool the system, and one or more standby fans that automatically are placed in service should

• Intelligent Fan Control

• Electrical Considerations of Fan Cooling

The article covers the electrical considerations for connecting the cooling fan of Power Amp Design power op amps to the signal circuits. All of the power op amps currently produced by Power Amp Design rely on an integrated heat sink and fan to provide adequate cooling for the amplifier

• How to Make a Fan Talk

As the fan is running view it from the side. You will be able to detect any "wobble" or. misalignment of the blades relative to one another. A fan in good condition should have all. three blades superimposed appearing as a single blade. You can use a Nova Strobe to inspect for bent pulleys

• How to Select a Low Noise Fan

The total sound power produced by the fan can be calculated by the empirical formula below. The formula yields the Sound Power Level (PWL) in decibels. Logs are to the base 10: PWL = 55.2 + 30Log VT + 10Log HP. Where: VT = Fan tip speed in ft/min x 10-3. = P x DIA. x RPM/1000. HP = Input Fan

• Re: Ceiling Fan problem

1. Buy a new fan. 2. Tell us what kind of fan it is. 3. Look on the manufacturer's website for a schematic. 4. Buy a new fan. Welcome to CR4.

• Re: samsung rt28 double door refrigerator.

More than likely the fan that circulates air from the freezer compartment is not turning. In the US there is usually an envelope somewhere on the back or the compressor section that has a schematic that will help you check the circuitry that powers the fan once you determine that the fan hasn't fail...

• Re: electrical oven

Hi, pgsath! Sorry, never actually built a dehydrator before, although I've used one at home to make food for camping trips. My girlfriend usually dries herbs on something like a clothesline, and knows which ones to dry right-side up and which ones to dry upside down. But I Googled a c...

• Re: revered a.c.

There are several possibilities here. The fan motor could have reversible connections to change the rotation.....but unless it was replaced, most factory motors are fixed in their rotation direction, its cheaper that way. The other issue is that the compressor and fan motor typically have a common...

• Ceiling Fan to Permanent Magnet Alternator

Hi all! I only have an AAS in Electronics and that was 9 years ago. In my job, I very seldom have to pick up a multimeter or read schematics anymore so I have forgotten about everything I learned. I love experimenting though and this is one of the experiments I want to try. I saw this youtube video...

• Re: Refrigerator Running On and On and On

Greetings. The compressor, it's fan, and evaporator fan (one by evaporator coils in freezer) are controlled by the fresh food thermostat (look at the wiring schematic usually with the refrigerator) and the defrost timer. If the defrost thermostat or the the defrost heater are not working then y...

• Toshiba Launches Driver IC for Small Fan Motors

TOKYO--(BUSINESS WIRE)--Toshiba Corporation (TOKYO:6502) has launched the industry''s first1 digital- control-type sine-wave driver ICs for single axial fan motors, which are used in products like refrigerators and PCs. Single axial fans are often used in eco-efficient home appliances requiring low noise and low energy consumption and for cooling PC servers. With recent increases in the capacities of PC servers, as many as 6 to 8 cooling fans are sometimes required in a single unit. In these appl

• Aluminum Wired Fan vs. Copper Wired Fan

Dear Friends; Some years before, the fans produced in our country were wired (winding) with copper wire but now a day, fans are also wired with aluminum winding wire. The point which confuses me is that, for example, ceiling fans in local market, are available with following specs; Copper

• Are You Ready for Mandated Fan Efficiency?

Over the past few years ASHRAE, AMCA and ISO have all created standards that can and will be used to mandate minimum fan efficiency via specifications and codes starting NOW or 2014. AMCA Standard 205 covers fans with an impeller diameter of 5 inches or larger and a fan shaft power of 1 hp an
