Thank you, that's what I needed! Mike

I have an old Fox cart. I need a bearing for the rear axle. The bearing fits in a couple of flanges that allow the bearing to swivel in all directions for proper alignment. The outside is rounded to allow it to swivel. What do you call this type of bearing and where can I get them...

That motor kit is about one HP, I think that is more power than you need. I'm guessing you only want this to go walking speed. I read the description it says "Easily move 400 Lbs (181 Kg) at top speed of 18 MPH" Walking speed is more like 3mph. If you only want walking speed?? you could get by...

For safety I would have a handle to push. When the handle has pressure against it a switch would close allowing power to the wheels. When you let go of the handle the unit would stop. Mike

Ya, kinda neat how the diodes just direct the flow of current so it only goes one direction. There are a couple other schemes to do this, but they are not important now. Probably, it sure would be helpful if you could get a schematic from the company. (hint, hint) The few wires has me...

How much current do you want your circuit to deliver? For a decent amount of current and efficiency a boost converter would be a better way to go. I have no idea if the T200 toroid is the big enough or if it is the right material. Here are some links to boost converters...

Ya, that's close, but you need to go a little farther into the circuit for the voltage measurement.. The transformer secondary connects to the board and delivers A.C., then (4) diodes on the board convert it to D.C. You need to measure that D.C. voltage and then you can you can use something as...

I think the one I showed has a low voltage (5v?, 12v?) that is used to power the circuit that develops and controls the higher voltage (95v?) that is PWMed to control the motor. PWM is -pulse width modulation-, it is a way to control motor speed that does not waste energy as heat. Look it up...

Interesting Idea! One possible problem is the board may (probably) has some low voltage control circuits and you would need to find a way to supply them. I don't find any schematics on the net but I did find this block diagram from an instructible...

The treadmill motor is rated at 95 volts so if you use 48 volts It will only put out about 0.4hp to .66hp but should last a long time. The 100 watt motor on 48 volts will put out about 0.5 hp but probably won't last long. The starter motor, I don't know, they aren't made for continuous...

Ok, 100 watt motor at 24 volts, that will draw about 4.2 amps, however you can double that when you start from a dead stop and accelerate with a large load (that's you). So let's say you could draw 10 amps under large load. As an example we'll pick 12 gauge wire which has 1.62 ohms of...

Ok, 24 volt do you know the wattage or hp? Mike

I don't see why you need a clutch. A clutch allows you to get the rpm of the motor up so you have some torque to move the vehicle. An electric motor has all of its torque a zero rpm. The controller allows you to start slow so you have good control. Here's a page with a graph of torque for an...

I have to say "I don't know" If you look over the electric car forums rarely does anyone use a transmission. http://www.diyelectriccar.com/forums/ It is true that when you first jump on the throttle it draws a large current but the quickly comes down as speed increases. I suspect any driving...

I don't get it! What part is overkill? Mike

Hey guys, I'm looking for cogged pulleys and belts for my electric gokart. These are also called synchronous pulleys or belts. My motor has a 3/4" shaft and the axle is 1". I want about a 3 to 1 ratio. Maybe 20 teeth and 60 teeth. The problem I have is mostly, finding pulleys with the correct...

What is the purpose of the torque converter with an electric? I can't see any reason to have one. In case you haven't watched it, here's a kart my son and I put together. http://www.youtube.com/watch?v=5MKjbXltAew Mike

No doubt, an electric costs more than an IC gokart. No chance you can spend like the liberal (socialist) president. :-) I don't know what controller you had, but if I was buying my controller again, I would go with the programmable just for that little faster ramp up time. Although I don't...

My background is electrical/electronics. I have a dislike of working on oiling engines and gasoline smelling carburetors. And, an electric gokart is something a little different than the usual. :-) Mike
