well there’s your problem. 
no, seriously though, it seems brushed motor are slowly being phased out, because of the constant maintenance it needs to keeps operating. namely the ‘brush’ being worn out.
Look at the rpm-torque curve they show. Cutting corners off a triangle can give you a flat torque curve at the start, or a flat drop to zero at the RPM limit but the electronic control system doesn’t change the basic properties of a DC motor.
With ESC tuning for electric motors you can adjust their torque at a specific rpm. For my R.C. cars there is a setting called boost which can replicate the effect of a turbo with a boost of torque at an rpm you can set (by changing the timing, the advantage being you can get high-end power while still keeping it from overheating) and so its probably possible to do a similar thing to make the motor produce a set torque throughout the entire rev range.
interesting page though… if dc is really that advantegous, why is does tesla use AC motor?
@rcracer11m isn’t that just a PWM controller? with an extra ‘feature’ for the higher frequency range?
If I remember correctly, AC induction motors are fairly simple, not exactly hard to manufacture, and easier to control, all of which makes them ideal for electric cars.
Im not sure what a PWM controller is I’ve always heard them called ESC’s (electronic speed control)
PWM is Pulse Width Modulation, basically what’s used in brushed-motor ESC’s and a whole bunch of other applications. Essentially, it takes a constant voltage, 12 volts, for example, and turns it on and off really, really fast (we’re talking thousands of times per second or higher) to effectively make a lower voltage out of it.
Brushless electronic speed controllers also use PWM, but they’re working on three phases, generally. I’d go into how they work, but I don’t know exactly how they function at a core level.
Please stay in topic now. Open another thread if you want to talk about this. We are in 1967 and we have to build a buggy.
I already have - I was actually taken aback when some users diverged from the current topic. Now I would like to ask you one question: if mass production is not a requirement (and I assumed it wasn’t one), will it still affect a car’s placing in the final standings?
Edit: I know what a kit car is, so mass production won’t be necessary for the dune buggy challenge. Parts which cannot be mass-produced are thus fair game.
not assuming anything, but do you know what a kit car is??
First Order Automotive would like to present our rear engined, rear wheeled drive buggy, Angry Bug.

i was toying with using the A35 body, but i was never happy with the looks. i’m too vain.
Sure, but I don’t know if Der Bayer would agree with you in his assessments about the costs and convenience of the entry.
They are alright. Just have an eye on the costs.
yup, that’s the part where i’m a bit worried about. pretty sure we’re slightly above average
You want a buggy, you got 55hp of beach furry, the Smooth Bugalicious!

A1 name.
Looks like we’ve struck the same chord here… Earlier today I sent in the Howler Dune Rod '67.
…the hood scoop is for cabin air.

Great minds think alike
How did you get this line thick on one end and progressively thinner on the other?
