[PSUBS-MAILIST] enquiry - Propulsion

["steve" <steve@kobol.worldonline.co.uk>]

Hi All

i have a question regarding propulsion but not for surface travel.

I am trying to research (small ROV size) thrusters with a magnetically
coupled shaft but am not able to find much on the subject.

my own design thrusters are ok but i am having to look at filling them with
oil to maintain the sealing.
i would like to do some experimenting and was wondering, is there anyone on
the list who has built such a device or can point me in the right direction?

any ideas would be appreciated
