First of all, I am a beginner when it comes to ev conversion.
I am considering converting a light (600kg) vehicle. This vehicle has an ICE engine with these data
power 20 kW @ 6500 rpm
torque 40 Nm @ 3800 rpm
displacement 600 ccm.
At 6000 rpm (ICE with gearbox in fourth gear) the car drives 100km/h, 62 mph
I am considering using this engine: Toyota Prius Gen2 MG1
alone, without MG2, no planetary gear unit,
no counter gears, no differential gear etc. like this
"viewtopic.php?p=62245&hilit=yamaha+yz#p62245". I would like to use the engine with the original transmission in fourth gear (adapter plate, couplet)
I plan to do this with the Prius Gen 2 inverter. This is necessary in Germany.
And I wonder if a Toyota Prius Gen 2 MG1 (not MG2) would be suitable.
Now I'm a bit confused about the MG1 performance figures in different sources:
In this study
there are numerical values for the MG1 motor:
Rated Voltage (V) AC 500; maximum output (kw/rpm) 37.8 /9500, MAXIMUM torque (Nm / rpm) 45 / 0-6000
-> My question: Is there really a continuous torque of 45 Nm between 0 and 6000 rpm?
This source is about the MG1 of the Prius Gen 3:
https://journals.sagepub.com/doi/full/1 ... 4020962624
MG1 maximum speed, 12,000 rpm
MG1 maximum power, 25 kW
MG1 rated power, 12.5 kW
MG1 maximum torque, 80 Nm
The graph there shows that 40 Nm rated torque are available up to approx. 3000 rpm, but then there is a drop to 20 Nm at 6000 rpm. This is normal for these engines.

Could you continuously get 25kw of power and 45 Nm of torque up to 6000 rpm out of the engine (MG1 Gen 2) when accelerating to 62mph on the motorway?
Could you use the more powerful MG2 section of the Gen2 inverter and use Johannes' board to control this MG2 section of the inverter to drive MG1?
(And of course, cooling and lubrication must be ensured for this....)
Many thanks in advance for your advice!
