I know what a DC is. I think i'm sure about what an AC motor is, But what is an AC/DC motor and why is it different from an AC motor?
There is a type of motor called a universal motor or an AC/DC motor that will run on AC or DC (usually the DC voltage required is lower than the AC required). These motors have no permanent magnets, using instead an electromagnetic field coil. The reason these work on AC is because the field coil polarity reverses along with the armature coil when the AC source reverses, keeping the attraction between the two coils in the same direction. Most portable power tools and vacuum cleaners contain these motors, although they aren't intended to ever run on DC. They are popular for tool applications because universal motors also happen to be very powerful for their size and weight. A typical 115 volt universal motor will run just as well on about 30 volts DC.
It may be referring to the fact that the motor has AC coils and DC magnets. Not all motors use permanent magnets. They actually have a separate DC source for the magnets.
it will be difficult to hand turn any motor fast enough to illuminate a bulb that large. You could put a volt meter on the motor while you turn it to see how many volts you get. You can also drive one motor with another motor, just to see what the best voltage possible is. A DC motor will generate DC voltage, and the DC voltage will likely be small - approx 12 volts or less. If you spin such a motor fast enough to generate 120 volts, it will self-destruct, because it's spinning ten times faster than it's designed. There will also be inefficiencies, so you will only get part of the electric energy out. You might want to try a smaller bulb, like a flashlight bulb.
Well, there isn't much of a difference but an AC motor must be plugged into a wall outlet for example. A DC motor can run on a battery such as a car battery.
AC = alternatinc current thats the best i got bro sorry
