Is a Dynamo Slowed Down If the Output Electricity Is Connected to a Separate Electric Motor?

Sure is. The losses in the windings and friction of the motor, plus the load on the motor shaft, extract energy from whatever is driving the generator (that is, dynamo.) To explain it another way, current flows through the dynamo's windings to the motor. This current creates a magnetic field in the dynamo's windings, and this magnetic field creates a torque that opposes the power source for the dynamo. If the motor was frictionless and had no resistance, then the dynamo would not slow down, but that's not generally the case.

1. How do I get an electric motor to work without having to start it by hand?

Sounds like you got a bad motor, or the voltage is wrong. Is it 120. or 220? Check the label on it, or take it to your hardware store

2. what size electric motor should I get for my 3 wheel bicycle?

no such thing as a 3 wheel bicycle - that is a tricycle bicycles have 2 wheels, unicycles have 1 wheel by the way, this is for Cycling, and in Bicycling try the Motorcycles category

3. The electric motor discovered my Micahel Faraday?

The electric motor converts electric energy to physical energy, albeit in a circular motion. A motor that has fixed magnets within can also be used to convert physical energy back to electrical energy (generator). If you think about it, what would the world be like without motors to blow a fan, start your car, run your old record player, or CD player, pump water, etc. Without motors, we would still be cutting wood by hand (no electric saws) and most factories would be so much less productive than they are now. Almost anything that runs on electricity and involves any kind of circular motion has a motor in it. Without the electric motor, we would all be living by very limited means.

4. Can Gear Box Electric Motor be used for wind power?

That motor is geared for slow speed, 30 rpm. You would need to have a slow turning rotor with significant torque.. The transmission on it may contribute a significant amount of friction. It looks like a permanent magnet motor, but it does not say that, I would make sure it is a permanent magnet motor before you buy it.

5. Quick Electric motor Wiring question(pool pump)?

Unfortunately, the cable is out of focus, but if the end is frayed, and appears to have broken off somewhere, look for a terminal with a frayed end sticking out of it. My guess is the terminal near the red line, where the line makes an angle. There appears to be the broken end of a crimp lug, like the one that holds the green wire. Look closely at the remnants under that nut and see if something was broken off, as it appears. Then get a new lug and a crimping tool and crimp the black wire to it, after removing a bit of insulation. But if my guess is correct, there is part of the lug missing and it could be down inside somewhere.

6. What are the techniques to increase the power output without decreasing efficiency of Electric motor?

Most well designed electric motors are over 90% efficient, and that number is higher for larger motors, approaching 98%. So your best approach is to use a well designed high efficiency motor to start with. Other important factors are: 1. power efficient speed control because you can lose a lot of power there if you are not careful. 2. Well designed dynamic braking system to recover power normally lost to the brakes. This impacts the overall design as you need to keep extra capacity in the battery so the dynamic braking system has someplace to dump the power. .

7. im looking for an electric motor with very low speed and extremely high torque?

200 RPM is 3.3 per second, which seems fast for what you want. Certainly I would not describe it as very low speed. And 300 pounds of force seems excessive. What you are missing is the travel of the piston, you need that to get the torque. Anyway, this is all in picking the right set of gears, which lowers the speed and increases the torque. If you want a travel for the piston of 2 inches, that means the diameter of the drive is 2 inches, and with 300 lb, that is 300 lb-inch of torque or 25 ft-pounds. which is 7.6 meter-pounds or 17 meter-kg or 160 N-meter. Power for the motor is 160 Nm x 2 x 3.3 RPS = 3400 watts or 3.4 kW or 4.5 HP But I think 10 pounds would be more than enough instead of 300, so that becomes 100 watts, a much more practical 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...
