I am planning to make a custom chopper sized electric vehicle (Im guessing it will be under 200 pounds) and I am using the tips and techniques that are in the Sparky guide. I have some questions though (I have never built anything like this before) and would appreciate help.

1) I am looking to get the speed up to around 40 MPH, so I went looking on the internet for a motor. Since the Sparky motor is 2000 watts, I thought that I would need a higher wattage because this is a larger vehicle, however , I cannot find any motors over 1000 watts anywhere.

These are the ones that I am considering:

http://www.technobots.co.uk/acatalog/Online_Catalogue_500W_to_1000W_Motors_77.html#a147 0_2d060

I am not sure if these will suffice because they are only 1000 watts. If these won't work, where can you get a motor like Sparky's? What type of vehicle could have a motor that I could take out?

2) Can any DC motor like the ones above be connected with a speed controller?

3) What type of wiring do I use to connect it all together? Do I need some type of connectors to put on the ends?

4) How does the battery charger interface with the batteries? I know that on retail electric scooters they have a connector on the scooter and a charger that fits into it.

5) What type of welder would be best for this project? (I cant spend over $500 on it)

6) Should I have some type of cooling fan?

Thanks a lot for your help, I don't have anyone to ask.

I will answer my own questions:

1) That's not good enough, search for a better one around 2000 watts or more.

2) Yes

3) Pull wiring out of something and buy some connectors somewhere

4) wire-feed welder

5) No

I'll send pictures when Im done with the project

For motors in the 2000+ watt range, I know of two that are quality made.

The original Sparky motor...

The mighty PMG132...

The first motor will run at 2000 watts with no problem at all. The second motor will put out more than 10,000 watts. Yes, ten thousand.

I plan on using the 10KW motor on a tandem motorcycle this year.

Thanks for your advice. So, being that I will be building a heavier vehicle than Sparky, should I get a bigger motor, or will the Sparky one suffice? Im not in the market for one as big as that 10000 watt one though. By the way- how do the teeth for the chain connect to the motors, and can they connect to any motor? I am thinking about going 36 volts in my system. How can I ensure that I will connect the speed controller up properly, without frying it? WHat if I wanted other parts like charging outlet, key start, light? Where can I find out how to connect these items properly? Thank you very much for your help

Hi all
I am new to the forum. Have not built anything yet but am dreaming and looking. What is the actual manufacturer and name of the motor used in Sparky? The link posted does not work.
Thanks

Hi presyesc and steerling, welcome to the site. Like Joey, I can't answer the specific questions you asked but didn't want you to feel unwelcome. Keep asking as you move your project along and hopefully we will be of help.:1eye:

Thanks guys.
At this point I am only at the sourcing parts stage. It seems like all the new motors that would be ideal for a project like sparky need to be purchased online at a place like cloud electirc or evehicle. I would have thought that there would be local suppliers in most major cities but I haven't been able to find anything yet.

Thanks for the updates links Brad!
I have an old stick welder in my garage, and within a few weeks I hope to have a friend who welds come over and we will see if we can get it going. Gotta work with what I have!
