Paul and Sabrina's Cheap 3 Phase Inverter (AC Controller) with Field Oriented Control

[e*clipse]

@Astro:

Yes, starting with one front, one rear. As I learn things I'll be going to one per wheel.

I didn't remember that e*clipse was Frederich! Hello Frederich!

Hi Paul!

Yes, it's me - I'm barely keeping up with you!

I can't tell you how happy I am that you've pulled this off!

The encoder bearing is the same one as this eBay listing.

75kw rewind in a 132m frame - is there a typo there? My google search gives a 7.5 KW/10 hp motor, about 20 inches long, 165 lbs, 1800 rpm, 60 hz, in a D132M frame size.

I tried to shoe-horn a 30 HP, 575VAC 286T frame 3 phase AC direct drive into an S10. The motor weighs over 600 lbs. I was not successful

What motors/drivetrain are you using? Sounds like an interesting build!

I am still trying to figure out what AC motor I will use

I'm going to be using the Toyota MGR's from a Highlander Hybrid. In the Highlander Hybrid, they used an electric rear drive along with the gas/electric front drive. They are basically the entire motor/gearbox/differential in one unit weighing about 100lb. They are rated at 50Kw each. My final evil plan will lock the differential and use one MGR per wheel. The differential will be electronic, using one motor controller per wheel.

By the way, ( Sorry this really is the wrong thread ) I've got one of those Siemens 3ph AC motors that were used on various OE EV projects like the GM S10 EV. It's brand new and I'm selling it for a fair average value or maybe an interesting trade...

I think the 75kW may be peak not continuous.
On the Custom EV Performance web site it is called the "75kw AC induction EV motor".
75kw AC induction EV motor customevperformance.com
I think it weighs about 82 kilos (180lbs). Carrying it around is a bit of a task. The only "handles" are the front and rear shafts and they want to turn making it difficult to maintain a good grip. If i have to move it again i will see if i can weigh it.
Hopefully i will be getting a loan of my brother-in-laws engine crane (crane, lift, hoist, whatever they are called) in the next week or so which will mean i will not be lifting it manually again.
It will also be when the ICE engine is plucked out of the car never to burn petrol again. This will be the second time i have lifted an engine from a car. I learnt the first time that doing it by hand, even with a tiny 1.4litre engine, is not the best plan.

What voltage is it wound for?

Sounds like a good application. I'll check around and see if one of the local (in Canada at least) Highlander Hybrids has had a tree jump out in front of it ... and become a source of parts (salvage wreck).

100 lb for the motor, gearbox and differential is AMAZING! I may even call Toyota and ask what a replacement costs. Likely $20K but I should ask

The Siemens motors appear to have a tightly coupled and engineered interface to their intended gearbox. The adapters that I have seen are very interesting but are several levels above my fabrication expertise. I would need assistance to get it into the car.

ALSO off-topic (sorry) Right now I'm trying to fit a Warp-11 Series DC motor into a Mazda MX6. It's about 2 inches too long and I can't QUITE get that from removing the aux shaft. The metal itself on the fender as well as the shape of the metal appears to be an integral part of the car's structure ... so I don't want to remove any more than I already have
