EV Motor Not Powerful Enough? Make Your Own.

Many of us have tried our hand at the ol’ electric car conversion hack. Yank the engine, throw in an industrial DC or AC motor, and bob’s your uncle. Simple stuff. But if you can’t find just the right motor for your application… why not design and build your own brushless DC motor?

This mind-blowing build is by an electrical engineer who decided to design a 45kW motor (that’s 60HP). That’s not a typo. Design and build a 45kW motor! He has a video series on the design process which includes the CAD and all the calculations he did to make this thing work. Once he had the design complete and ordered the custom parts, he started building it.

In his living room.

700+ hp electric Honda S2000 built by High School senior

[Juan] dropped us a note to let us know about a little project he’s working on. A few years ago, he bought a Honda S2000. It served him well, but now he’s converting it to electric power, and it’s going to be a beast.

[Juan] is using 104 battery packs each containing 4 cells in parallel. The total output of his battery assemblage is 686 kilowatts, or 920 horsepower. [Juan] is assuming his drive train will be 85% efficient, meaning his wheels will be getting 782 horsepower and 1500 ft/lbs of torque at 0 rpm. Yes, this thing is going to scream.

A project of this caliber is usually undertaken by gear heads with decades of experience, but that’s not the case for [Juan]; he’s still a senior in High School. A build this awesome can only portend a very bright future as an engineer and certainly a few drag race wins. This car is going to be a monster, and we can’t wait to see it on the track.
