Q:I had a 350W AC motor that did not work for this purpose. Do I need to have a DC motor? Also, what type of battery should I use? Obviously, it must be rechargeable so should I go with a lead-acid battery? This system will have a human-powered crankshaft, a motor, a battery, an inverter, and will need to produce 100W maximum to charge my laptop battery through the inverter.

what is the motor for? use a alternator! and a car battery, for recharging purposes. OK hook a alternator to a bike, hook the alternator to the battery, then the battery to the inverter, plug in your computer and start peddling. as far as AC,DC goes, remember AC is highvoltage, DC is low voltage

Q:There were no dealer of solar panel here, so I decided to buy the solar board which will arrive by next week. How can I make the AC motor work if I can't connect the solar board to the AC motor directly?

I would pick up some books on solar panels make sure you get one that has information with basic electronic information. Solar panels make a dc voltage in most cases unless it has some type of inverter built in this would be rare. Depending on the size most are low wattage. I would guess it doesn't have the power to run the ac motor even if you could. If you could you would need a voltage regulator and a inverter to turn the dc to ac. You would need some type of battery to use as a capacitor. Your best bet would be to charge a battery system then buy a inverter to run off the battery and a battery charger with built in regulator they're cheap check OKorder.. You could put the motor on a timer to give the panel time to charge the battery before running. This is what i would do if i wanted to say pump water for cattle on a low budget.

Q:So,i wanna ask is there the motor will become short circuit?

It depends on what you mean by opening the power supply. If you mean switching it on, yes, there is a good chance that you will burn out the motor. It does not sound a very useful thing to do.

Q:I want to bypass having to get 4 deep cycle batteries for my project. I need to power 2 24v 200w motors. I was considering a 2 cycle 1000w generator. I know I need an AC to DC converter, but what kind would I need in terms of stats. (Watts, volts and amps) would it just be better to go with the deep cycles?

There is no deep cycle generator. You need 24VDC 500W generator. A 1000W 24Vdc, generator would be plenty. 4 cyc/e would be much better because 2 cycle is really noisy. Deep cycle is a Battery specification.

Q:I need to know how to basically look at an electric motor (either salvaged or new) and be able to tell what rpms it can achieve, what torque it is capable of delivering/withstanding, and what voltage requirements are needed in order to speed up/slow down/optimize performance. Also, is there a way to distinguish whether it is AC or DC? Take as much space as piossible in order to explain this and/or provide links. I really want to learn as much as i can about all different aspects of applying electric motors to designs.

I'm not an expert in motors, but let me give you some info. You won't be able to deduce all that info just by looking at it. But most all motors have a name plate that has voltage and current requirements. It will also have a manufacturers name and a model number. You may be able to look that up and get more info. The number of wires coming into the motor will help. 2 wires and ground, and it's either DC or single phase AC. 3 wires and ground and it's a 3 phase delta motor. Look for a box on the side of the motor with a capacitor in it. That is probably a start capacitor, and this is probably a single phase AC motor. If you can see inside the motor, and you see brushes (NOT slip rings) then it's a DC motor. You can also look at where the motor came from to get clues. read the references .

Q:3phae 440v ac motor, having star and delta connections

Contact the manufacture of the motor to see if possible and how to.

Q:Causes of insulation breakdown in AC motor voltage withstand test

In the withstand test, the test voltage is too high and exceeds the specified value.

Q:We are using single phase AC capacitor start run Induction motor.I want to know the same motor can be changed to three phase motor or not.If it is possible what are parts i have to change.

Not possible.

Q:Which price is higher, AC motor or direct current motor? Which one has a longer service life?

Exactly, if it is of the same size, should be AC motor, low price, long service life, AC motor makes the rotor rotating by electromagnetic induction, relative power, and internal heat production is less than that of dc;

Q:HOW DO I REPLACE THE AC FAN MOTOR IN A 1993 AUDI 100CS?
