My diesel motor broke down, so I designed and installed an electric motor drive.
Great about this project is the way I used different prototyping techniques to fab the timing pullys, and the alu frame.
And even more great is that compared to the diesel engine which had 4 separate liquid systems and electric system – this has just one electric system, and it doesn’t pollute or require any maintenance.
It charges on solar panels 20V boosted up to 60V for the 4x12v batteries (series) that provide the electric power. -I have even been sailing on sun alone 😉
V.1 10kW BLDC 150KV 45-52V 86Ah direct drive – not working 🙂
V.2 10kW BLDCmotor 150KV 45-52V 86Ah timing belt over cast pullys. Worked ok but at low rpm for the motor, causing high current draw.
V.2 25kW BLDC motor 50KV 45-52V 86Ah same timing belt setup, this works perfect from 150 w just driving the boat in harbour without current or strong wind up to approx 2000W in canals etc.
If you are interested in more details, just ask.
I will try to get some shots from the current installation.. to show the pulley setup.
