I understand the future will include more and more electric conversion vehicles so during the pandemic I decided to design my own using only hand tools.
I designed this to be an efficient 10Kwatt system using a PMAC motor, various Aluminum parts, a 600 amp Kelly motor controller and 72volt LiFePo4 battery bank that employs a BMS, charger and 500Amp contact. I also used an aluminum 2:1 gear reducer to keep the RPMs low while doubling the torque.
The basic chassis, pictured below. I designed using electronic schematic software even though its not electrical at all. Its 1/2" aluminum plate and pipe. No welding just all bolted together.
This is a partial mock up with most of the components installed.
I mounted this system in my 20,000 pound sailboat so every connector is watertight and of aircraft quality - think gold plated.
Below is the 7.2Kwatt LiFePo4 battery bank. I ordered the 24 battery's off Alibaba directly from the manufacture. I hand cut each Nickle plated bus bar and drilled each hole. Took a few beers that day.
Total cost of the project is about $4,500.
Forgot to show the unit installed in the boat.

Re: My 10Kwatt Electric Motor
whoah..nice... really cool how small the motors got nowadays....do you know how much Nm it has? and can you charge while on sea, like with solar modules?
Re: My 10Kwatt Electric Motor
Dude, nice work! You've effectively built yourself half of a ~$300,000 boat (ballpark guess) for under $5000
It just goes to show how simple of a concept electric vehicles are at their core. They're basically scaled-up versions of the RC cars some of us played with as kids
So... when are you gonna show us your electric airplane?

¯\_(ツ)_/¯ It works on my machine...

This is brilliant. Times they are a changing!
