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:can you connect a 1/4 hp ac motor directly to the output of ac from a windmill or turbine?

Yes,you can,but not stable.

Q:what is the difference between ac servo sewing machine motor and dc servo sewing machine motor?

One requires alternating current to run, and the other requires direct current. Choose the one that fits with the power supply feeding the motor.

Q:In a motor, in the middle, coils are used and they are magnetized when AC current flows through them.I have found permanent magnets are being placed fixed with some distance around these coils for producing deflection and thus the motor runs in some motors.Does a 7.5 HP AC motor also has permanent magnets?

Unlikely, most ac motors are induction motors. If your 7.5HP motor is 3 phase, which is most likely as it seems large for single phase, the rotor will be what's called squirrel cage. This is aluminum bars made into a cage. The rotating magnetic field in the stator induces a current into the rotor, the same way a transformer does but the resulting magnetic field produced is opposite to that of the stator causing the rotation. Smaller single phase motors may contain windings and there are a number of different types of single phase motors. Larger 3 phase motor may be wound rotor so that some resistances can be added through slip rings for starting or speed control. There is a type of ac motor called synchronous motor. The rotor is powered by dc and is, in effect, a large magnet but this type of motor is not self starting and uses some other method to get up to speed before the dc is applied.

Q:What are the advantages and disadvantages of AC and DC motors?

The DC motor is easier to control than the AC motor. It can be applied to a wide range of speed regulation. It can be used in power braking, but it is more complex and more complicated than the maintenance of AC motors.

Q:Is household sewing machine good for AC motor or direct current motor?

If the family is good with two kinds of machines are good, each have their own advantages and disadvantages, their love for what kind of home use which, if not good with the pedal sewing machine, low price. Do you use the factory electric sewing machine, Erqianduoyi taiwan.

Q:How to change AC motor to generator?

The motor can be changed, or diesel gasoline engine as power drive, and capacitor connected to the motor at the outlet of the can, the capacitor adopts non polarity capacitor voltage, then Y must be greater than or equal to 250V, the delta connection pressure is greater than or equal to 400V. conditions must have left the rotor when the rotor magnetic remanence, no. With 6V DC motor in the three-phase one electrically connected to a few minutes, the rotor will produce remanence. Its efficiency is very low, three-phase motor with 4 poles. The speed is 3000 rpm. The maximum is 75%. after the transformation can only be used as emergency power. Do not try, there is not much sense, but can be used as academic discussion. The basic will not be adopted, too much waste, and here is the capacitor capacity at the discussion

Q:All I have is a motor, fan, a plug, and about 5 or 6 wires sticking out of one side. How do I get the motor running?

It's an AC motor, you can't run it from DC, which is what i assume you mean by power supply. Someone answered this question the last time you asked, with details on how to connect the wires to an AC outlet. .

Q:ac motors

There is no formula to combine two motors driving a common load. There is a means of doing this and it is called a differential drive . This might help you :

Q:Im trying to make tattoo gun what would be a better motor 18volt ac or 18 volt dc?

DC because it's safer. If you don't know what you are doing you could kill someone with ac, even at 18 volts.
