Idaho BS thread in the PNW

Bah dun pss

I get it

 

It is the power converter that converts the DC back to AC for the 120 outlet in the bed. haha

I wonder if cars will stay DC forever or if they will eventually go to AC. Although, the rectifiers on the alternators can't be that expensive anymore I'm sure.

 

The Tesla Roadster uses a three-phase Alternating Current (AC) Induction motor.

I haven't ever looked, but do they have a transmission or do they rely solely on a variable frequency drive to change the speed of the induction motor?

Or do they use a combination of both?

Now that I think about it, pairing a CVT transmission and a variable frequency drive on an induction motor you could have that motor screaming at the max torque value the entire time while accelerating. You could literally have a flat torque curve at the rear wheels on your peak value. That would be badass!

 

The wide torque band, particularly the torque available at low RPM, eliminates the need for gears – the Roadster has only a single speed gear reduction; one gear ratio from zero to top speed. Switch two of the phases (this can be done electronically), and the motor runs in reverse. No need for a reverse gear. Not only is this design incredibly simple, reliable, compact, and lightweight, but it allows a unique and exhilarating driving experience. The Roadster accelerates faster than most sports cars and whether driving on windy mountain roads or cruising down the highway, there’s always instant torque.

 

Yeah I remember hearing about that. Electronics can work very quickly. haha And like you just said they must rely entirely on a variable frequency drive to change the speed. That is pretty awesome! Any idea what RPM that motor can rap up to then?


For my final project in my lab we are using a variable frequency drive to adjust the speed of a synchronous motor. We are going to hook it up to an induction motor to supply a counter torque and measure how the speed affects the pull out torque of the synchronous motor.

I've been playing with motors all semester and just took a test yesterday on how synchronous, induction and DC motors work. Not fun, way too many different equations for each motor to remember and to mix up between all 3...

 

well of course..as do most small electronics and devices.

and thats what so cool about em.

 

Is that a female with you!?

 

I was going to say the same thing! haha

 

She's actually smiling in the pics too.... How'd you manage this Ben??? Haha

 

I think thats the other truck not ben. Where is this? Im guessing about 45 min from me?

 

Ahh, hard to tell! It was the first thing I noticed but I just thought it was like a lot of your pics that make your truck look black. The same cb antenna location fooled me as well...

 

Bahaha! I wondered when I saw this pic:


Just figured you grew your hair out or something haha To be honest the green and black look fairly similar in the pics. haha

 

Opposite sides though. Ben's is passenger and that guys is driver.

 

hahaha i was like..wtf..when did your truck go black Ben? your over editing! then i saw your truck for reals..

thats the new guys truck/girl guys.

Ben..is single and green as ever.

 

how can you throw rooster tails? your tires are so far in its like a someone sucking in their gut..

 

no they all look good..

i was saying when i saw the first few pics i was like...wtf..your truck is black now..

then realized it wasn't your truck.

follow me?

 

Reminds me of a bad luck Brian.

Buys mud terrains to shoot rooster tails in the mud, bought skinnies...

 

Holy cow Ben, I didn't realize how tall your truck was compared to a stock height truck!

And how did it happen that you two put your antenna mounts in the exact same place? Are you trying to be twins lol?

Also...green and single as ever,
That's out Ben

 

sheesh..its like no one pays attention to Ben's build..

Ben's is on the passenger side..not the drivers side.
