What Must Be the Power of the Electric Motor If the Car Is to Travel at a Speed Of?

So the motor must supply exactly 1197N. So the torque on the motor is based on what gearing ratio you have. The current on is based on the torque/speed curve for the motor. Basically, there are too many variables missing to do this calculation correctly.

1. what is the advantage of having an electric motor on the hubs of electric bikes?

The less stuff you have between the motor and the wheels the better. Everything you add just increases friction, and that uses more energy. So if you can get rid of a chain that is one less source of friction.

2. Why does a small 120 vac motor take more power than a larger 72 volt electric motor?

The smaller motor's start up or primary windings require a higher start up wattage for higher torque

3. which electric motor is best for generating electricity?

you are in touch in a dynamotor. it really is a unit containing a motor and a generator. Many militia radios from international warfare 2 used 12 volt means from automobiles and used a dynamotor to generate 250 volts to turn on the vacuum tubes. You look to have an interest in making 33,000 volts from one thousand volts at 5,000 watts. this can artwork, besides the indisputable fact that the most contemporary you would possibly want to draw from it really is 5/33 , that's 0.151515 Amps at 33,000 volts if it were one hundred% useful. As all and sundry else observed you wo not be able to get more beneficial than one hundred% performance, and in practice dynamotors were extra like 30% so the utmost contemporary you would possibly want to get may be about a million/20 amp. do no longer attempt it with out professional help because 33,000 volts will leap about 2 inches by ability of air and a million/20 amp is more beneficial than sufficient to kill someone

4. Where can I get a powerful electric motor?

Find an electric golf cart. It will give you all the basic parts you need

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

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

6. How can a battery with a specific power output 340 W/kg with a weight of 600 kg produce 581 kW in power from the electric motor ?

Theres probably some unit issues here. Batteries will have a specific Wh per kg, but not watts per kg.Watts per kg is not a usually specification nor can it solve the problem

7. How do I grow up the speed of an electric motor?

The speed of a three phase AC motor is based on the following: speed of the rotating magnetic field = 120 x frequency / (number of poles). So, a 4 pole motor (sometimes referred to as 2 pole pairs) operating with a 60Hz voltage source, would have a speed of 120 x 60 / 4 = 1800 rpm. Increasing the frequency will increase the speed. Increasing the number of poles will decrease the speed (this would require the motor to be wound so that the number of poles can be selected). That would be the rotational speed of the rotor of a synchronous motor. An induction motor's rotor would be a little bit slower, around 1750 rpm at full load, but around 1795 at no load. There are other types of AC motors, too. Generally, the frequency is the key parameter for controlling the speed. n The speed of a DC motor is based on the following: speed of the armature = (magnitude of the DC voltage on the armature terminals) - (armature current * armature resistance) / (magnitude of the magnetic flux produced by the field circuit). Changing any of these parameters will cause the speed of the DC motor to change. Increasing the armature voltage increases the speed. Increasing the armature current (by increasing the mechanical load) decreases the speed. Reducing the field current will increase the speed. n All of this can be found in a textbook on motors, or on-line in Wikipedia, with a more in-depth explanation on the how's and why's and what equipment can be used to control the speed of either AC or DC motors.How do I grow up the speed of an electric motor?How do I speed up the speed of an electric motor?

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...
