1970 Opel GT - Forklift ACIM - Project Log & Inverter Build
Posted: Sat Nov 09, 2019 12:59 am
Figured I should create my own thread here rather than butting in on the actual controller threads.
The purpose of this thread is mainly the inverter side of things, and the electronics side of things, since the braintrust of DIY EV electronics seems to have gravitated here.
I won't re-document the mechanical build itself, (including patching together 2 junk cars into one less-junky car), the bulk of that is over at the DIY EV forum here: https://www.diyelectriccar.com/forums/s ... 00587.html
It's the ugly one in the back:
Long story short, it's a blend of 2 cars, sold after the previous owner's passing, that I drove 3000 miles to save from being scrap metal. I paid $200 each for them, and I'm trying to do the build as cheap as possible (ala Damien's $1000 build), and has a bit of a theme of using unwanted or garbage items (not too strictly).
...
I'm planning on using a Forklift ACIM I saved from the scrapyard.
It's a 36/48v, 3ph, 6 pole, rated for 961 RPM.
Rated:
13 kW continuous.
18 kW for 1 hour
37 kW for 15% duty cycle (450 Nm)
I think I'll need it spinning around 4800 RPM to go highway speed.

I actually haven't even tested it yet (no inverter to test it with).
The big one here:
It weighs 255 lbs (116 kg):
Shop towels for scale:
I think I'm planning on deleting the transmission (which I don't have anyway) and direct driving the prop shaft.
...
I picked up a Gen 2 Prius inverter from a crashed car for $150, but it lacks cabling.
Seems in good condition:
I also picked up a Gen 1 Prius inverter for $24, just in case it'd ever come in handy. Maybe electronics projects in the future:
...
And I picked up the inverter cooling pump, only to discover that they famously fail on Gen 1s and don't throw an error code unless the inverter overheats, which it almost never does. Pump appears shorted. Hrmph.
...
I can use a soldering iron, and understand basic electronics, but everything done here is over my head. I'd like to contribute back to the community by documenting my progress and being a good first test case for the controller Damien's building for the Prius Gen 2s.
