Q:I need to convert DC power to AC?
First of all, remember that the AC signal can be at most, in a perfect world (which ours is not), equal to the wattage of the DC input. 5 VAC (RMS), at 1 A, will require a 5 W DC input. In practice you should at least double this. The technical term is an inverter. You can buy an off-the shelf inverter and connect it to a transformer. Since you're shooting for low voltage, you can also just build one with a 555 timer and a power transistor that can handle 1 A. You'll need to filter the output (with a big inductor or an RC bridge) if harmonics will be a problem. The quickest simplest way to do this is to build yourself a dynamotor by connecting the shafts of a DC motor and an AC motor. You can very easily generate this kind of power, and it will be exceptionally clean and noise-free, unlike the output of an inverter. But you have one other option: a cheap PA amplifier (remember, you only need 5 watts) and a sine wave generator (which can be any wall transformer with a large resistor in series to prevent excessive current from flowing). Just turn the volume knob until you get the voltage you want. If the whole rig needs to be able to run on DC, you can construct the sine wave generator out of a 555 and an RC filter with a very low cutoff.
Q:How do I program my Arduino to control an AC motor and a digital temperature gauge?
You need to be a LOT MORE descriptive about what you are trying to achieve, how fast the response times must be, etc. For all I know from your description, you have an AC motor driving a fan which blows air over a nichrome wire that is being heated by some fixed current and you want to adjust the fan speed so as to appropriately maintain a fixed temperature on the nichrome wire... with no mention of how you measure that temperature. You are FAR FAR away from providing anywhere near enough specification to get any help at all.
Q:Is the motor of a washing machine AC or DC? ?
I have seen both depending on the make and model. Certainly ac is used more often but since the motor is often speed control then it doesn't make that much difference which is used as there is some form of controller anyway. The dc I came across was a permanent magnet type and was actually the reason the machine had broken. A magnet had detached from the body and jammed the armature.
Q:An AC motor is running at 90% full load rating continuously. is it ok or need to upgrade to higher capacity?
Running at 90% load should be fine. If you upgrade to a higher capacity, the motor will likely be operating at a less efficient load point, wasting energy and costing more to operate.
Q:Motor Controller for AC motors?
Q:Rated speed of AC motor
Synchronous motor speed, =60* frequency / magnetic pole logarithm8 pole: 60*50/4=750 turn / min, asynchronous speed slightly down about 735 RPM / min.6 pole: 60*50/3=1000 turn / min, asynchronous speed slightly down about 980 RPM / min.4 Pole: 60*50/2=1500 turn / min, asynchronous speed slightly down about 1475 RPM / min.2 pole: 60*50/1=3000 turn / min, asynchronous speed slightly down about 2970 RPM / min.
Q:Can I convert a electric motor into a generator suitable for use in wind energy production?
Maybe try Popular Mechanics or another such source. Don't forget that you actually want to construct this thing in a safe and suitable manner. Maybe place some calls to companies that make wind energy windmills for personal usage, such as powering a small house, etc. Say that it us for a small school project. You might be surprised, as they might want to help you out with suggestions and the like.
Q:can you connect a 1/4 hp ac motor directly to the output of ac from a windmill or turbine?
I imagine it can be connected, but the output of the ac motor will be determined by the output of the turbine at the time. If the turbine is under-supplying power, the motor will under-perform; if the turbine is oversupplying you risk the ac motor burning out. Referring to the specifications of the turbine will help determine if its a good idea to connect it directly. I believe most windmills are designed to limit rotational speeds for safety and durability reasons - so such turbines do tend to have an upper limit of sorts (and i think this can be manually changed at that - angle to the wind etc).
Q:what is the hp of the largest electric motor.?
Q:DC motor speed control performance is very good, why do we need AC motor?
AC motor: a machine used to convert mechanical energy and alternating current energy. AC motor has become the most common motor because of the great development of AC power system. Compared to the AC motor and DC motor, because there is no commutator (see DC motor commutation), therefore has the advantages of simple structure, convenient manufacture, relatively strong, easy to make high speed motor, high voltage, high current, large capacity. The coverage of AC motor power greatly, from a few watts to several 101000 watts, even millions of kilowatts.
