High Speed electric motors High Torque electric motors. To start Electric motors AC vs. DCIll just put this plainly you cant use an AC motor in a go kart. Sure, it would be technically possible, and some electric cars use AC motors, but those are with 1. Get the latest breaking news across the U. S. on ABCNews. com.

AC stands for Alternating Current and is what comes out of your wall socket. Its used because it transmits long distances better along wires from the power plant to you and doesnt electrocute people quite so badly. DC stands for Direct Current and is what comes out of a battery. Its plain electricity, and its what you want to use for a go kart. To get more technical, AC is called alternating because the polarity the and reverses in the AC in your house, it happens 6. An AC motor needs this. The ideal solution, of course, is to ban cars and melt them down into free bicycles for all. But in the real world, your best bet is to physically avoid the pollution. Now, it is possible to make AC out of DC. Fear 1 Pc Game Torrent. Most people have seen inverters, which you can plug into you cars cigarette lighter and then plug in a laptop, blender, whatever. Why not just use one of those The answer is current, and power. For a good electric go kart, your power demands are going to be around 1. Because of surge current. An electric motor is an inductive load. Have you ever seen your kitchen lights dim when the refrigerator or microwave comes on Thats because those are both inductive loads, and inductive loads require a TON of power to start. Say some electric motor might need 2. Your 1. 00. 0 watts kart motor starting under load might need 5. Go price a 5. 00. Yeah, you dont want to do that. You might think that maybe you can make it work even though some people say its a bad idea trust me, Im one of those people who chases down bad ideas to see what will happen.

So to be clear, you cant reasonably use any AC motor in a kart unless you want to go no further than your longest extension cord. That means dont bother with any motor marked AC or which comes out of a washing machine, belt sander, or anything that plugs in to the wall. There are two exceptions to this treadmills and really loud power tools. Most treadmills use a 9. DC motor the treadmill contains a rectifier which converts the AC to DC.

I wouldnt use either a treadmill or universal motor either. Why not They are made for 9. US and not very powerful. Car-Insurance_category.jpg' alt='Low Insurance Cars For Young Drivers Uk.

All drivers must undertake a defensive. The Toyota Prius p r i s is a full hybrid electric automobile developed by Toyota and manufactured by the company since 1997. Initially offered as a 4. While a treadmill motor might seem like its powerful, consider that youre going to have to carry around at least seven batteries of car battery size to get enough voltage and power. Its the same as with the inverter technically possible, but as a DIY go kart maker, its not what you want. OK, thats all bad news. Whats the good news Well, there are plenty of DC electric go cart motors out there perfect for go karts. What should you look for in a DC electric go cart motors Low voltage. The lower the voltage, the fewer batteries you have to carry around. Also, if the rated voltage is lower, you can overvolt the motor, which gives you more power. Say you get a 2. 4v motor you could run it on 3. Could you run it on 4. Yes. but for a very short time. Why Well, putting that extra voltage in a electric go cart motor causes extra current to flow, which is where your power comes from. This is a problem because the more current that flows, the hotter the motor gets and when it gets too hot, it will burn up, explode, and leave you standed. What happens is that the insulation in the electric go cart motor is rated for a certain lifetime say 2. If you double that temperature, that rating may drop to say, 1 year. If you get it really, really hot, it might fry in ten seconds. Dont overheat your motors. You could do a 1. You could do a 2. You could do a 3. I wouldnt put more than 4. DC. A person with dry fingers can touch both terminals of a 1. However, do it with 1. Thats because it takes a certain amount of voltage to overcome your body especially your skin resistance. Once theres enough voltage to overcome that resistance, youre being electrocuted. It only takes 0. 0. If youre going to make an electric go kart, you need to educate yourself on electricity safety. I wont write that book here, but go read up on it and dont put more than 4. Note Im not saying 4. Okay, safety lecture over. Where can you find good motors for electric go karts D D Motor Systems, Inc The last thing Ill talk about with electric motors is their power ratings. There are two important things you need to know electric motors are rated for continous power, meaning they can make that power all day, all night, for years on end. Gas engines are rated on instantaneous power, which is how much than can produce for a moment. Secondly, electric motors produce maximum torque the force with which it spins the wheels at zero RPM. Have you ever ridden a two stroke dirtbikeAll the power comes around 5. THEN you get power. Electric motors are the opposite you get all your acceration at the very start, and it tapers off linearly as you speed up. This makes for very fun take offs if your batteries, controller, and motor are up to it. What this means is that you have to think about electric power ratings differently. A Harbor Freight 6. HP gas motor might be fun, but a 6. HP electric motor is nearly 5. W 1. HP and will rip your face off and melt your batteries. Sweet. You can use much smaller HP rated electric motor than you would a gas motor, and have the same amount of fun. So, how do you throttle an electric motor You have three options onoff control likely to fry something, progressive onoff control with multiple batteries, and a controller. Onoff control is where you just have a big switch or more likely, a big relay or contactor and you get full power as soon as your throw the switch. I wouldnt recommend this, as the surge power phenomenon which I mention above means that youre switching on a LARGE amount of current all at once, and quite frequently what this will do is actually weld the contacts of your switch in the closed position, which now means that youre sitting on a kart which is at full throttle and wont turn off. I know a person who tried something like this on an electric motorcycle and has the scars to prove it. Unless its small motor and big big switch, Id avoid this. How about progressive onoff control Simply, this means that you are switching on your batteries one at a time. Say youre running a 2. Youll have three 1. What youll do is have three switches relays. One will switch on the first 1. The second will switch on both the first and second, giving you 2. The last will switch all three batteries into the circuit, giving you full power. This is much less likely to kill you. I wont draw up a diagram for you, but there are some out there to look up. Ill warn you that if you just draw one up, its easy to wire things up such that you are dead shorting a battery, which could weld your contacts cause the battery to explode if you are unable to break the circuit. Be careful.  Be careful with this because your first battery to be switched on is going to drain much faster than your last battery. You will need to charge your batteries individually not in series and stop driving immediately when your performance with the first battery ionlyi starts to decline. You will permanently damage your batteries if you over discharge them. Lastly, you can use a controller.
