Dear all,
I am looking to convert our 1970 Fiat 500L into an electric town car, and having undertaken quite a lot of research I have tentatively dipped my toes into the EV pool with the first acquisition- this being a Dana TM4 IPM 200-50 low voltage permanent magnet ac motor. Performance wise the motor is apparently capable of 20kW peak power at 96 volts. The only data sheet I can get from Dana shows its performance at 48 volts with a corresponding peak power output of 16kW with a peak current draw of 450 Arms. Torque is 70 Nm at 48 volts. For comparison, the ICE powered performance figures for the 650ccengine version are 24bhp (18 KW) and 41 Nm torque. I am pretty happy therefore that the Dana motor should be adequate to at least match or improve on the ICE performance.
I am currently working up designs for adaptor plates and couplings to mate the motor to the existing gearbox, flywheel and clutch.
My next purchase, unless you all tell me the motor is a dud, is to purchase an inverter/controller. To this end I have researched Curtis controllers, but they are not cheap!
Does anyone have any suggestions for an inexpensive 3 phase 450Amp peak controller, or perhaps a working used one that someone is looking to recycle?
I like the idea of an open source controller but my electrical/electronic skills are pretty much non existent so it would have to be plug and play. I am also very happy to use used parts from a salvaged EV, but not sure which vehicles would be suitable to look at.
For batteries I am thinking of using second life Nissan Leaf Gen 2 modules hooked up in series to produce 72-96 volts. Range I am looking for is a real world 60 miles.

Any and all thoughts/contributions will be great fully received.

I am at the very start of this journey so please excuse my ignorance.

Many thanks

Nice project.
have you considered the VW ID3 Battery
