Many thanks for your replies on this specific point, nice video
The lynch motors are good, but for a 45' boat, 72v is required (stepping out of the 50v DC safety thread hold). Futher, I had been told that regeneration with a Lynch is really not easy, and it needs more complex electronic than a controller
My choice was HPEV AC20
I could easily reach 8 knots with the boat in a 20-25 wind. The antifouling is three years old, I towed my dinghy and I need to replace a stay. So, I get only 6 knots at the speedo. I could get a little regeneration, but nothing.
The shaft spins, I can see it but I can't really count the rpm, it is too fast. I estimate a 4 to 5 rps = 240-300 rpm. The 5/1 gearhead gives 950-1500rpm motor spin. When switching the system on, it stalls at less than a 60 rpm at the prop shaft. Not enough, I guess. By engaging the throttle slightly, I read a consumption of 1 or 2 amps.
When I receive the HPVS motor, there was an error in the phase. I had to connect the U to V and V to U terminals of the controller and motor.
Could it be an explanation to the problem? Any possible incidence for the motor regeneration? Should I play with the W terminal?
Cheers
Fred
Regarding regen, I've always found this video fun and luckily they have a bigger boat with decent speed and therefore regen:
