Shaft seals For those of you that have ever had the pleasure of working on a washing machine, they have worked out the problem of shaft seals long ago, the...
Hi Pete, I know these seals exist, however the situations described are quite different from the situation I want to use them in. In both the case of a boat...
Hi, Has anybody tried making an RPM-Torque curve for LRK motors? I am wondering how much torque LRK motors can deliver at low rpm. Low being 50 - 100rpm. All...
Hello, Why not to use magnetic clutches (couplers), uses eddy current when perm.magnets or current of motor when electromagnetic coupler. I have not any...

hi Stefan, Yes, it is true, And I spoke that my model has been made 40 years ago ;-) There was brushed motor, of course, and prop shaft has just bronze ...

Nick about those seals, here is a spec by one manufacture on this type of mechanical seal Range of application Temperature : From cryogenics to 200C Pressure :...
... for low rpm (ie low eddy current) what about magnétic bearing ? and no need for axes ! you can design magnetic bearing with conic air(water)gap and with 2...
Here is an interesting article about low rpm rotor 600 to 800 rpm for heli. It was tried by Paul Arlton, when he was developing the first model for LMH..he...

I have not used Dymax, but I use Loctite 326 and 7649 activator. I have made several hundred CDR motors with 5x5x1mm magnets and the adhesive works very well. ...
Hi Herbert, I use the Dymax 846-gel. It works very well just be sure to remove any particles stuck to the magnet with masking tape and clean the parts ...
Ach so! Thanks, Then I need to order and try, Mostly I use special two-component Metal Adhesive(Schüco Metallkleber Artikel-Nr.298 354) but petrify takes...

I'm not so sure this is a recomended practice for good comonent reliabillity. In any case, another great way to both solder and remove SMT components is a...
Stripping a printed circuit board for surface mount components is very easy with a heat gun. And most of them fall off without any harm done and with fully...
Hi everybody. Does anybody know if annealing the magnetic backing for the magnets in an outrunner makes a difference? During production gas and water pipes get...
I do not use gas or water pipes for making the rotor bell. From local car-knackery you can find <car cardan driveshafts> with different diameter. They are made...
