Boat Forum / Building / July 2007

I have a traditional dutch anchor winch with two speeds a chain gypsy
- vertical - and a drum end. One shaft has a sprocket wheel to enable
it to be motorised. I have decided to go electric and would like to
fit an electric motor. The winch maker recommends 750 - 1kW at 50-60
rpm. I am now trying to source a suitable motor and it seems that I
need a motor with a gearbox to reduce the 1440 or 2880 rpm down to
50-60 - assuming a 1:1 sproket gear ratio. I think the motor should
also be capable of providing an effective brake when not turning - ie
when the winch is clutched in to raise the anchor and chain, the motor
holds. Motor can either be mounted on deck - IP65 - or underneath the
deck - IP20 or so.

Looks like an in line gear motor with a brake that has a manual
release so that the winch can be used in normal hand mode.

Would welcome any other thoughts??
