Hello, my name is Michael. I go to computer and electronics school.
I have a school project i’m going to build with a friend in my class.
My school pays for the project, but we have a budget at around 550 dollars.
We are going to build a tankchair, similar to this.
Personally, i have a lot of electronics experience. My grandfather has a workshop and he has teached me a lot.
I have built an RC tank and a quadcopter before. My friend knows a lot about cars and how they work and he can also weld.
Now for the questions. I was thinking of using Turnigy Aerodrive 6374 on 12S.
I had to find a 12S ESC. I will be using two motors, one per track. I will be gearing the motors a lot,
i am going for torque not speed.
After a lot of research, i found this ESC: http://www.wheelspinmodels.co.uk/i/85118/
But when i looked through the forum, i found out that using a VESC was the best option, one of the reasons are
that normal ESC’s have a chance of smoking. I have read that normal ESC’s are not made for a vehicle you can stand on.
I found this ESC: diy-electric-skateboard-kits-parts/vesc-the-best-electric-skateboard-esc/
I am thinking of ordering that instead, it supports 12S and 240 Amps burst.
The problem is that i want tank steering. I will control the tank with
one stick from my radio. When i move the stick forward i want both motors to move forward,
when i move stick to the left i want one motor to spin forward and one backwards.
And i don’t want any brakes. I want the motors to move from forward to backwards throttle without any braking.
I know the ESC is programmable, but i just want to be sure.
Maybe someone has a suggestion for a better ESC. It can’t be too expensive though, i have almost blown the budget!
im not sure how you will realise it with this budget, but good luck
if you want to go 12s with high output, you´ll need two 12s escs, also i would pay attention on getting sensored escs, because you´ll need to move the motors from a standstill.
What you linked is a VESC from DIY and it´s only 50A continuos.
With 2 of these you´ll be able to generate about 4,4 kW with 2 motors.
Widely used are these: diy-electric-skateboard-kits-parts/torqueboards-12s-120a-car-esc-opto-hv/,
Also tested and used in some applications like Mountainboards are the “Robbe Roxxy Blcontrol 9100-12 Opto”
Have you considered brushed motors? You would get a slower speed and constant torque. Plus they are eaiser to controls. Brushed motors run hotter but cost a lot less than brushless.
yes but i made this that is wat i woud do btw these are on and off switches the toot phatel stil needs to be conected to the mottor
and whif a bit of hot glue i can make them one
