Thank you Doug for your input, and appreciate your interest. Not easy to solveĀ
If I understand well, it will be more easier to use a DC system to control the motor. But is the DC motor has to run on batteries only, or he can run directly from a DC genset (I try to avoid abtteries beside the one for the starter)
What is the device needed to control the speed and the reverse rotation of a DC motor?
Is the cable to transfert the current from the genset to the DC motor will be to huge? I was thinking about that when I thought about the AC three phase. My washing machine is on three phase AC and looks very simple to control and the wire is very normal normal in size. This was the start on my thought about using a AC three phase. But a washing machine and a electric motor traction for vessel are rather different I suppose!
It seams that the cycloconverter is the aparatus used to control the AC motor. Is the cloconverter can also reverse the rotation of the motor?
Thank you all for digging in your own knoveldge and to share it with me. I am learningĀ
