    Kelly KLS & Revolt RV-160E watercooled : cogging noise and overheating

    Thank you, I did remove the motor from the boat, was not easy, and just opened the motor. Well... everything that could burn did burn. The reason : i had to move the boat (9 hours) to go back to its port. Since the Revolt had stalled and partially burnt the week before, it shorted some...

    Kelly KLS & Revolt RV-160E watercooled : cogging noise and overheating

    Thank you, I think I would need a complex setup to fit in the tiny space, maybe a 90° right angle gear + a pulley & belt. this is too much modifications for right now, I will look at that option next winter. Do you think it is feasible to rewind just removing the cover of the motor (without...

    Kelly KLS & Revolt RV-160E watercooled : cogging noise and overheating

    Thank you both, you were damn right ! It actually went very bad just after I posted my last message, I tried to fix weird controller throttle issues, the motor stalled at startup and burnt in awful toxic fumes in few seconds. It was medium rare, it is now well cooked. I just hope the...

    Kelly KLS & Revolt RV-160E watercooled : cogging noise and overheating

    Thanks a lot Lars for the clarifications The brushed was a pancake motor, larger and thinner. Its reduction ratio was 1.47:1, with a nominal 2300 rpm under 48V. Ideally that ratio would have been 1.7:1 due to the propeller, which I could not change because it matches the Volvo motor. In...

    Kelly KLS & Revolt RV-160E watercooled : cogging noise and overheating

    Thanks Lars, i read your posts about rewinding the Revolt and improving the cooling, what a journey ! On the E version Revolt put the sensors on a PCB to improve their placement. Do you think it will still benefits from new sensors & encoder ? The problem I have with a belt is it takes way...

    Kelly KLS & Revolt RV-160E watercooled : cogging noise and overheating

    Thank you Fechter, the Kelly KLS controller has a sine wave output and has a learning mode that automatically tries and find the combinaison, moving steps by steps. Since the controller has completed that process and the motor is running (from rpm 50 to approx 900, neutral and reverse without...

    Kelly KLS & Revolt RV-160E watercooled : cogging noise and overheating

    Hello, Since I upgraded my boat to brushless I added acoustic noise & vibrations to my thermal issues. I am obviously disappointed since the cost (about 2000€) and all my efforts in this migration. I hope to find here some expertise to help me understand my mistakes and options. My 6m...
