The shop is working again.
I did a test drive at 22°C (72°F) outside temperature with the now closed hood.
On the Autobahn the Soliton1 reached the 65°C (150°F). While the controller alarm started to blink he changed from 14 KHz to 8KHz and derated the motor current.
Liquid cooling is not an option. It's a must.
In search for the best working and best looking place under the hood.
This will work and can be welded together..
