I have been playing around with the EM57 motors in the frame again. Looking for a way to fit one motor for each axle.
Since the front / rear axles are in a different work shop for renovation at the moment I couldn't test out how the prop shafts would look like. But I believe that the rear one will be rather short with a steep angle and there will not be enough space for a reduction gearbox. Unless it's a LWB (which my series IIA isn't). The newer 2*320 Nm motors would be to prefer to get enough wheel torque in that case.
Alternatively could the rear motor be suspended to line up with the axle somehow to allow it to move up and down. 🤪
The front one still needs to come further down in order to let the body rest on the frame.
Another crazy idea would be to flip the rear axle over so the rear offset is to the left instead of right and fit both motors under the mid seat. This would still mean that the rear prop is very short and the front very long...
Disadvantages
Requires 40 kWh battery to avoid power surge at full throttle.
Requires 2*320 Nm motors (I only have 2*250 Nm available at the moment.) 🤑🤑🤑
Not that high wheel torque, if no reduction gear is fitted.
Advantages:
No diff lock needed! 😆
No problem to keep up on the highway! 🤣
Very efficient with low losses!
40 kWh => pretty long range!
I think this is something for future projects! If I ever build a tough Defender 110" or Toyota Land Cruiser !?
