Hi oscaryu1, I'm curious about your 8:1 gearing; What is the diameter of your tire? What is the maximum motor RPM? Mike

I run my gokart at 3:1, but I have a more powerful motor and four car batteries. Mike

The batteries I have are taken from junked cars and are not good, they only lasted about 30 minutes before we recharge. The plan is to get new larger deep cycle batteries when we get the kart put back together. The motor was surplus from a military lift of some type, I found the controller...

I looked at the controllers on the site, each controller has a wiring diagram with it. But I'm guessing, you don't have an off the shelf motor? Gotta know about the motor before anyone can tell you how to wire it. If you can, pick a controller that is the proper voltage and has a high enough...

NO! no! just riding, oh ok, a few donuts. Ya, I'm thinking about a larger chain and sprocket number. Here's a video. http://www.youtube.com/watch?v=5MKjbXltAew Thanks, Mike

Quite the wit Mackey, Do a search of PWM [pulse width modulation] That's what is used instead of a variable resistor. I doesn't waste nearly as much energy in the form of heat. Show me what controller your looking at and your motor or at least something similar and I'll try to help. Hey, I'll...

Hey guys. I have worn out sprockets way before their time. I'm on my second motor sprocket and about to get a new axle sprocket. Please see the picture I have attached, note the shark toothing of the teeth. This is an electric gokart so I have loads of torque. That may be part of the problem...

Hi All, During some repair work I removed the brake from a my 60s Fox Karts gokart. The part looks damaged and I wonder if this is available anymore. Where can I purchase this part, just the internal section. I don't want to change the braking system just the part. Thanks, Mike

How is that relevant to "Electric Projects"?

I think if you find a forklift motor designed for 100 + volts, it will weigh more than the rest of his gokart. Mike

Here's the schematic I used for my kart. Some of it will apply and some won't. The shunt/resistor circuit probably won't apply to yours. Should give you a good start on the wiring you need.

I have no knowledge about Curtis controllers, but it worked on their golfcarts! You might be able to get some info on this forum, http://www.diyelectriccar.com/forums/ Scroll down the controllers. Mike

Hey dabruno, I forgot to mention the spline thing with most golfcart motors. You need a support for the motor shaft. The original Neurotikart at http://www.neurotikart.com/ shows how he did it. The rpm, I don't know if there is an ideal rpm, it will just require a higher sprocket ratio. Mike

Less noise, no messy grease. Mike

I don't have a quick answer, I just got lucky, a welder, marine hydraulic repairman friend of mine had disassembled a military lift of some kind and the motor seemed useless to him, an oddball 28 volt motor. I was asking everyone if they had or knew of any DC motors that I could get, he said I...

I don't think you have enough hp for that. The motor on my kart is rated 2hp at 28 volts 65 amps, however, I'm running 48 volts, when I floor the pedal the current goes over 250 amps. The formula for watts is voltage X current = watts, so 48 times 250 = 12,000 watts. If you divide that 746 to...

There are 746 watts in one HP, so your 1000watt motor is about 1-1/3 HP. (minus any inefficiency) I would pick a top speed say 20MPH, then find the circumference of your tire. Find how many rotations/hr it takes to to go 20mph. Then calculate the ratio using your motors max RPM. The units need...

Small correction, the (-B ) is a 35.6 amp motor. They may be a little light duty as they are for scooters, but if you kart is built light and you don't overload it with batteries. Note, each car battery can weigh 35LBS. I'd stick with 48 Volts that is not a heavy duty motor. The more amp...

Hey dabruno, Motor, Are you going new or used? Plenty of new to be found with a google search. Used, plenty of golf cart motors or a low voltage industial dc motors. Batteries, do plan on using lead acid or you going high tech? Decide on a system voltage, (may depend on the motor you get) If...
