How Is Hydrogen Used in a Fuel Cell to Power an Electric Motor?

Hydrogen is a flamable gas, which is a byproduct when you run electricity through water.(hydrogen cell) The hydrogen is then burnt in an internal combustion eng, and drives a generator, which powers an electric motor

1. How do you convert a household current electric motor to run on batteries?

Buy an inverter like you would put in your car to run your blender. It may have to be a large one for the power required for the door opener motor. A friend of mine once tried to use an inverter to make margaritas from his tail gate only to find the power was only enough to stir the margaritas.

2. if i had a 1 volt, 1 amp electric motor what would the battery specs have to be to pwr it it at full capacity?

Drawing 14 amps at 24volts will need a pretty large battery to run for an hour or so.It would need a pair of 12 volt deep cycle marine batteries connected in series to produce 24 volts.You've touched on the root problem with electric cars,it takes a huge expensive battery to barely do the job.

3. What gear ratio is needed to convert 1 RPM to 1,000 RPM from electric motor?

I am not aware of any electric motors that runs at 1 rpm

4. How do I control the speed of a DC electric motor?

Change the voltage supply of your motor. Increasing the voltage than the the specified rating will increase the speed of the motor. On the other hand, decreasing the voltage supply will decrease the speed either. You can also use a resistor in series with that to control the current. But it is more advisable to use the standard rating of you motor. Increasing the voltage might burn your motor. Decreasing the voltage will...well,,, waste your money for purchasing it because you did not use the full performance of your motor. Hehe. Look for a motor suitable for your project. Good luck for that :-)

5. How to put a electric motor on my longboard.?

one thing is, it will throw the balance of your board off...probably making it tough to use. the other thing is, and maybe i am wrong, but electric motors and water do not seem to be compatible.

6. Is there such a thing as a cheap and small electric motor to snap onto the back of a canoe?

go to wal mart drop 100 bucks on a trolling motor and 40 for the battery and have fun you may need a bracket if the back is not flat. But DO NOT put a 10 horse on the back of your canoe

7. Does an electric motor in electric cars wear out like gas or diesel engines? What's the estimated life for these electric motors?

Estimated time of service is 2-5x more than ice. Million km in definitely doable

8. How to wire an electric throttle to an electric motor?

Electric Throttle

9. how we can measure the wattage of a three phase electric motor which has no name plate?

If the motor is in operation you can use a clamp-on meter to measure the voltage and current of each leg. Power is Voltage times Current or sum P = VxI for each leg. This formula works if you know your line voltage and power factor angle. Power = the square root of 3 times Line Voltage time Line Current times cos(power factor angle). Each phase has its own angle so again you would need to sum the power of each together for the total power. P = 3 VIcos If the motor is not running, then you have to take even more involved steps. You will need to measure the inductance of each winding and calculate the impedance based on your line frequency. The North American grid is at 60Hz. Once you have the accurate impedance your can then use that to calculate the current for the rated voltage. Current = Voltage / Impedance. I = V / Z. Then you can calculate the Power as V x I. Again, that is for each leg and must be summed together for the total. Hope that helps.

10. An electric motor turns a flywheel that is connected to a pulley by a belt.?

The mass of the flywheel is irrelevant. Just there to confuse you. Find the angular momentum of the pulley. Find the torque required to accelerate the pulley. Find the force required for that much torque, given the radius of the pulley. That force is the difference in tension between the taut and slack sides of the belt. .

How Is an Electric Motor Conversion Kit Patent Eligible?
What is patented is defined by the claims. In this case there is only one claim (below). One thing to remember about claims. Long complicated claims where there are a lot of specifics are usually narrow and thus easily circumvented. Short claims are generally broader. In this case, there is a very long claim with many specifics. I am not sure why the examiner found this patent sufficiently novel, but I would say as an engineer, it should be trivial to engineer around this patent.An internal combustion engine to electric motor conversion kit system for supporting vehicle components in operative proximity to an electric direct/alternating current motor and for powering such supported vehicle components from the electric direct/alternating current motor, the supporting and powering being done in a safe, ecological, convenient and economical manner, the system comprising, in combination: a vehicle having a plurality of wheels and an operator controlled region,the electric direct/alternating current motor being within the vehicle, the electric direct/alternating current motor having a forward end and a rearward end and a cylindrical side wall, the electric direct/alternating current motor having a central shaft, the central shaft having a rearward section within the electric direct/alternating current motor and a forward section extending forward of the electric direct/alternating current motor, the central shaft being rotatable about a horizontal axis;a support assembly for retaining the electric direct/alternating current motor in an operative position, the support assembly including a central motor support and side motor supports, the motor mounts, the motor mounts coupling the central and side motor supports to the vehicle, the support assembly also including two vertically extending lateral brackets coupling the side wall of the electric direct/alternating current motor to the central motor support; a primary bracket formed with a vertically oriented first section removably coupled to the forward end of the electric direct/alternating current motor, the primary bracket formed with a vertically oriented second section rearwardly of and above the first section, the primary bracket formed with a third section perpendicular to and joining the first and second sections, an aperture in the first section in a key-hole shape for the passage of wires and the central shaft; vehicle components including at least one alternator and at least one air conditioning compressor and at least one power steering pump, the vehicle components being rotatably coupled to the second section of the primary bracket;a motion imparting assembly for driving the vehicle components, the motion imparting assembly including at least one drive pulley secured to and rotatable with the central shaft, the motion imparting assembly also including at least one driven pulley on the at least one alternator, at least one driven pulley on the at least one air conditioning compressor, and at least one driven pulley on the at least one power steering pump, the motion imparting assembly also including at least one idler pulley and at least one tensioning pulley, the motion imparting assembly also including at least one belt movable in a vertical plane and operatively coupling the at least one drive pulley and the at least one driven pulleys and the at least one idler and tensioning pulleys; a supplemental bracket secured to the second section of the primary bracket at an elevation above the third section, cable lines mounted on the supplemental bracket to increase and decrease the speed of the electric direct/alternating current motor and the vehicle; a radiator and a cooling fan, the radiator and cooling fan being positioned forward of the electric direct/alternating current motor to facilitate cooling of the electric direct/alternating current motor and the vehicle components; and a battery pack and controller in the vehicle for powering and controlling the electric direct/alternating current motor.1. how did michael faraday inventor of the electric motor change mankind?Electric motors transform electrical energy into mechanical energy the same way a steam engine transformed heat energy into mechanical energy. The source of the electrical energy was heat, but the electrical generator could be many miles from the electric motor. This was impractical with a steam engine if the steam had to travel very far through pipes. It made it possible to use mechanical energy in places where a boiler would be impractical. Electric motors could also be very small unlike steam engines which had to be at least the size of a car before they were mechanically efficient. Electric motors could also do something impossible to do with a steam engine. If mechanical energy was sent back through an electric motor it is transformed into electricity. This is the basis of electrical generators. It would be absolutely impossible to turn the wheels of a steam engine and generate coal.2. How can i increase the eficency of a Dc electric motor?Interesting reasoning, but there is one possible problem, and that would depend on the length of the race. If the capacitor is discharged at the beginning, then the solar panel is going to expend its energy charging the cap, rather than powering the motor. Once you get to steady speed, the motor with the capacitor may go faster by a tiny bit. Fair rules would suggest that you wo not be allowed to charge the capacitor beforehand. If you have an oscilloscope at your disposal, then I would look at the waveform of the current draw of the motor, when powered by the solar panel. You could then experiment with different size caps to see the power curve at startup, and steady state. Or, just determine which is best, if any, by running the car down the designated course length while timing it.3. Anyone know where I could get an RC electric motor with the following torque and RPM capabilities??...?Try rcuniverse.com or hobbyking.com but you would better check your specs. 100 rpm is VERY SLOW, and unsuitable for directly driving an aircraft propellor 50Nm is VERY HIGH torque. Both of these specs suggest an integrated gearbox with the motor, but then you would have to add a second gearbox to step the speed up again... Perhaps the "100 rpm" is actually the kv figure. That means rpm per Volt applied. If so, it's still a VERY LOW kv figure. kv figures above 250, and up to 3000 or so, are common. It might help if you give more details of your aircraft model. Maybe it's quite large...
