I am replacing my dead diesel engine in my sailboat.
I wish to replace it with a new diesel and an electric motor in parallel hybrid.
This would allow me to:
- Run the propeller using the diesel engine only.
- Run the propeller using the electric motor.
- Generate power by running the diesel and motor as a generator with a disengaged propeller.
In order to to do this I need a clutch so that I can disengage the propeller, please see the attached drawing.
- Bi-directional - must be able to go forward and reverse.
- Ability to engage/disengage remotely, electrically or mechanically.
- Stay engaged with springs. A power would need to be applied to disengage the clutch.
- Torque >= 600Nm.
- Does not need to be able to engage/disengage with differential shaft speeds, although it wouldn't hurt.
9.5488 x Power (W) / Speed (RPM) = Torque (N.m) =>
9.5488 x 50 000 (W) / 800 (RPM) = 596 Nm
I know that I won't get full 50 kW from the Diesel engine at 800 rpm shaft speed but I am using it as a worst case scenario, especially since the electric motor can generate a lot of torque during acceleration and develop much more than 20 kW for short periods of time.
My question is, do you have any suggestions regarding what clutch I could use?
I have spent days now searching the internet and I am simple out of my league. Please help with links to products, ebay or anything else that would help me find a clutch that would work.
I would love to be able to use something that is readily available such as the clutch that is between the engine and the gearbox.
I appreciate your help, thank you.
