Well gee, now I feel like a dunce. :wink: I wasn't aware that there was insulation on it! I thought copper wire was just that, copper wire. Now it makes sense. Thanks for clearing that up! :)
I understand how single layer/wound voice coils work, where the positive lead is at one end of the coil and the negative is at the other, but how do double wound coils work where both leads terminate at the top? See photos below for what I mean by double and single wound. On the double wound...
Indeed. We actually have two cars: one running a 4 banger (not sure which motor, since I'm not working on that car) that we'll run this year, and the electric one which will be complete next year.
While there are tons of brushless motors, very few have the specs we're looking for. The best fit for our application is the YASA-750, which costs $11k. They've already said they won't sponsor us. The motor we're going to use needs to be less than 10kg, output ~35kW, and fit our budget. Since we...
We're actually broke as ****. My dad's company forges structural pieces for Boeing's planes and is being generous to donate the blocks we need. Not pressed into the shapes yet, as tooling costs would be roughly $200k, but we have the tools to machine aluminum and titanium. If this were priced...
Look up what people do to their road/rally cars from Subaru and Mitsubishi. There are countless sites and threads from people who have twin blown their 4 bangers. However, why would you want to? On a small 4 banger, you certainly won't need that much boost and you'll have to figure out other...
I am on a Formula Student team and we have decided to design our own brushless AC motor. Our main issue is how we will cool the motor, since we want to keep weight down while also increasing power output. We will be making the rotor from forged Titanium (Ti6Al4V) and the housing from forged...
Homework Statement
This is exactly how this was written on the quiz today:
If f(1)=1 and f'(x)=(1/3) when x=1, find d/dx[f(2x2-x)].
Homework Equations
Basic derivative rules (i.e., power rule).
The Attempt at a Solution
The first statement simply determines that f(2x2-x) is...
