Now that is one big rotor - Page 2 - RC-Monster Forums

Think of how big the rest of the motor would be...

The motors we run in our trucks have 12-13mm rotors, and the cans are 36-42mm...that rotor is 62mm, so the can is around 200mm or so, which is pretty damn big!

They look close to 4" (100mm?) diameter if you ask me...

I wonder if a 200amp Castle HV esc would be enough....

Maybe once it was up to speed. I imagine the inrush current would be a few thousand amps...

Castle should be able to make a induction controller better then the AC Propulsion unit the Tesla uses.

Here's a little pic of a badboy we have over in the maintenance dept.
They had one out of the plastic sheeting, but I couldn't find it and could stay long to look.

Its something like 200A @ 440V. 88,000W :)

I'll see if I can get a better pic Fri.

The shaft is about 3"

Whoa.
That's some serious magnets in there..
I wonder how heavy that sucker is..

IDK, I was trying to figure out where I can put the batteries.

No magnets in them. Those are AC Induction motors.

I see..

*quickly googles up AC induction*

I see pallets almost daily at work. Generally the slats are between 2.5 and 3 inches

Chadworkz · 06.11.2010, 12:54 AM

I am pretty sure they are 62mm rotors, with 10mm shafts (12mm where the splines are rolled in).

Now, you'll have to clue me in as to your method of deduction. Arct1k posts a random pic, and right away you post dimensions. Did you and Arct1k collaborate prior to this post? Maybe you've seen this pic before, but Chris's content is usually original.

Are Arct1k and Chadworkz the same person? MY powers of deduction lead me to believe so.

History Channel, man...I watch more TV than should be allowed! They did a special on the Tesla car and talked about how the new electric power-system had never been seen or used before (all while I already owned quite a few brushless motors & escs, lol), and gave some specs about what powered the car. They lightly touched on the subject about how the electric motor that powered the Tesla car was different than standard electric motors, and gave some mildly-specific specs on it...and if I remember correctly (and with my brain I could be completely wrong), they said the part that spun inside the magnets was 62mm, while a cogged pulley was attached to a 10mm section of that "62mm part", where a belt turned a larger pulley (or it might have been one of those constant-velocity-transmission pulleys).

Anyway, I have seen a few things about the Tesla Electric Supercar on TV.
