I Need More Power For An Electric Motor!!!!!?

Question

I am working on a project using two motors taken from two hand held hair dryers, currently I am using 6 volts DC to power the motors for my project but I need more power(more than 50 volts DC) without the weight of adding extra batteries is there a way to increase the voltage without adding more batteries or plugging my project into the wall? and will increasing the voltage increase the motors rpms?

Answer 1

The speed and voltage have a correlation.

Motors from hand held hair dryer are usually 110v ac motors.
Get six volt motors of the right size and speed.

Answer 2

You should be more closely supervised by someone who understands electricity, and especially electrical safety.

You haven't told us any specifications for the motors, so I will guess they are designed for 110V AC. They likely don't care whether it's AC or DC. Yes, increasing the voltage will increase the RPM, but don't exceed their design rating.

Probably the simplest and least expensive is to use a 12V battery and an inverter. You could use a DC - DC converter, but it probably wouldn't be as efficient as the inverter and would likely cost more. Once you try either, you would likely discover that you have far exceeded the capacity of the battery.

You could try just using enough 6V batteries to get the desired RPM. But if you're running this for any length of time, think along the lines of a 12V deep cycle RV/marine battery and an inverter/charger. You can find the battery anywhere car batteries are sold. An RV/camping store is a good place to look for inverters. Look at prices before you start buying parts. It might be cheaper to just buy motors suited to your task and power source.

You can NOT just use a transformer, since they operate on AC, not DC. That's why I suggested the inverter or DC-DC converter.

Answer 3

If your motors were originally designed for 6 volts, an excessive increase(50 volts) will probably burn them out. Connecting your battery supply to a transformer could increase your voltage by a considerable amount-to the point of dangerous. If you are looking for more speed try gearing up the drive to the driven. If you are looking for more power try gearing down with a loss of speed of course.

Be cautious with power supplies.

Keep in mind that if a transformer that produces 1.5 volts is hooked up in reverse to a 1.5 volt battery , it will put out 110 volts.
Familiarize yourself with ohms law and study up on its components (voltage, resistance, and current) before doing to much experimenting.

Good luck and be very cautious

bear in strategies super plane require a lot of thrust to fly. electric powered automobiles (and particularly the batteries or cells) that supply that form of ability may well be uneconomically heavy with todays technologies. in addition they won't be stable over long distances, or might take an tremendously long term to fee. I agree substitute gasoline sources and electric powered automobiles are incredibly something effective to examine (which works on) yet i does no longer sense tender flying with an electric powered motor till i replaced into optimistic they have been stable, and there are nonetheless the themes of weight and charging time. moreover, a lot of issues in aviation are confusing to alter on grand scales as a results of strict FAA policies.
