Q:Hello, I'm thirteen years old, and II took apart this old small vacuum and it's as strong as a dang weed-blower, I cut the cord off and attached it with electrical tape and wire-nuts. And it is not one of the grounded motors either, it has a plastic case over the motor. It has a fan that sucks air from one end, and blows it out of the hole into the bag on the other end, also on the other side of the motor is a shaft possibly this wide: ----- so im wondering if it could be strong enough to move a 150 lb person?If so, how would I power it with batteries? (or even convert the AC motor to DC.)Thanks!

first of all, 0.02 amps will kill you. Second, this is an AC motor, it will not run at DC, or on batteries. Also, this is loud enough to cause permanent ear damage, get ear protectors. Torque depends on the gearing, and on the ratings of the motor. .

Q:3/4 HPVOLTS 230/460 1725 RPM FRAM 42CYZHZ 60

It is an AC motor and it is a 3 phase motor. Have an electrician, wire it up for you if it does not have wire with plug, since you have to ask this it is best that, you get a professional to hook it up. You can destroy the motor or worst you can kill yourself. It also should say single phase, dual phase or 3 phase, some place on the motor. If not, on inspection a good knowledgeable person can figure it out.

Q:I need to know what ac motors these are?

They look like standard industrial AC motors with a reduction drive (to slow the rpm down). You might call inmotion simulation and ask them what brand they use: 928.759.0631

Q:normally in VFD we taking ac convert into dc then chopped the dc at desired frequency and voltage then again convert vaiable dc into ac.my question is that why we require to convert ac to dc and control it why we not control ac power and vary the speed.

An AC voltage is a series of pulses, not a continuous flow of current like DC. With 60Hz we have a positive and a negative pulse 60 times a second. If we want say 37 Hz output, we have to store the 60Hz pulses in capacitors and then use transistors to output pulses from that voltage store at the different rate. We do not have control of the 60 Hz power frequency because that is set at Hover dam etc for the entire nation and the power grid depends on it remaining synchronized with every other power plant.

Q:Im wondering how many Volts/Amperes a regular small electric motor can handle.

DC motors are known for their longevity and ability to be overloaded without damage. Its hard to say what motor will take what though because some quality motors will run fine on almost twice the voltage while some cheaper ones will thermally break down very quickly. If you can keep a motor very cold you can probably push it pretty far, if you have a large supply for DC power and a LARGE peltier you may be able to get a dc motor over quadruple its rated voltage. At some particular point though the wire coatings will break down so over-volting a dc motor will eventually damage the motor.

Q:When you spin a DC Motor what kind of electricity is generater AC or DC?

You would get DC because the motor has a commutator to to pick off the voltage of a sequence of windings as they pass the position of the brushes.

Q:How do I change the speed of the motor?

There are several schemes. The 1. is to change the ratio of the mechanical driving wheel and driven wheel driven by the motor. The 2. is to use mechanical transmission to change the speed of the motor. 3. is to use electronic governor to change the speed of the motor. As for which scheme to use, it depends on your environment.

Q:Like if you wanted the motor to only spin 1rpm (unrealistic but yeah just for examples sake) would it still have the same amount of torque as it would at its rated voltage? If not is there any way to achieve this goal of instant torque and variable speed?

It varies a lot with the voltage. A neat way around this is to use an electronic box called a drive. A drive gives pulses of electricity to the motor, keeps same torque all the way down to very slow speeds. It also keeps the motor from drawing excessive current when stalled. An inexpensive drive for a 3 horse motor is about $300.

Q:I'm wondering about a homemade electric vehicle build using a 3 phase AC electric motor (leftover industrial application) and a Variable Frequency Drive inverter that accepts DC voltage input for the main power and a 0-10V speed input that could be attached to a quot;gasquot; pedal potentiometer. I could have these components for cheap/free if I wanted them, and I have a truck that could be used. Is this a plausible setup? Why or why not?Also, what is the recommended motor power rating for an average electric conversion? I'd like to be able to keep up with traffic at 65-70 if I need to, but I'm not interested in hot rodding around all of the time.

AC motor can't be used because it must be joined with wire to source and ac can't be carried.

Q:I need this for my lab report.
