Reverse-Trike EV

[Giovanni LiCalsi]

I'm building a reverse trike with two 15kw 20hp brushless motors with Hall's Effect sensors.
The motors will independently drive the front wheels and will provide limited slip.
It's motors will be mounted forward of the front axle and the battery packs with controllers will be mounted behind the front axle.
The motors will be powered by two 15kw 100volt Lipo battery packs.
Each individual motor will be connected to it's own electronic speed controller.
The controllers are PC programmable for low battery warning, high amp limiter, brake regeneration, soft start and high-speed governor.
I will be using a detachable iPad Mini for the dashboard that will also have remote ignition, GPS locator and Lo-Jack.
The wheels will be carbon fiber 17" Blackstone Black Mambas, as well as the rear single-sided swingarm.
The belly pan and lower body section will be made out of all metal Alulight aluminum foam panels.
It's upper body section will be made out of fiberglass.
The entire EV will weigh in at 800lbs. and have around a 75-100 mile range per charge.
It can take a 100% charge in 20 minutes.

Wow! I'll be following this one.

Could you reply and add stuff on a single thread ?

It is much easier to follow.

And obviously I very much like what you show us.

That sounds like a real beast with 40hp. I'll be living through you vicariously.

Here is the spec sheet for the motors.

Is it ok to stay on this thread?

I am using the 1906 Stanley Rocket body but reversing direction.
The front of the reverse-trike will have the curved shape and the tapered end will house the single wheel.
What is old is now new.

If there were any content in the other threads the mods can combine (or separate) them.

The Stanley is almost symmetrical. For the best aerodynamics the widest point should be at 30% of the length, in plan and taper. I don't know if the simple curve below the beltline and compound curved above is optimal.

Here's my design. The front suspension, steering and brake lines are in a filleted pylon. It's 3x12ft, the same as a P-38 drop tank. It has four wheels to fit into an open-wheel Lakester racing class.



It would actually be constructed of sheets braked into triangular or hexagonal flats , instead of being compound curved.

Very impressive drawing!

Freebeard, that is awesome!

A very unexpected four-wheel design, too!

If I ever finish my prototype Kamm-rack, I plan on cutting pieces of foam to fit together to make a foam-and-fiberglass version, so kind of like that, but I plan on sanding down the corners on the outside and filling in them on the inside.
