Good morning and Happy New Year! Balancing the rotor when it is a little bid longer than usually - How to detect where to add counterweight - forepart,...
Hi Herbert, The only modellers that I know have done balancing are the gas turbine guys. Members of the GTBA have designed a balancer. You can see a picture on...

hi David, Thanks - very interesting, but unfortunately they do not like to be more precise. But if to think about car wheel balancer (we can see in every car- ...
I guess they electronically measure the forces caused by the imbalance. If you know where the force is relative to a fixed position on the wheel you know where...
Herbert, Members are honor-bound not to divulge the design publically. It is documented in their old newsletters which are available to all members. Membership...
Just an idea ? Can't we use a heli gyro (turnable) and measure its max output ... Manu (@manu, manutoys, vantiv) ... From: lrk-torquemax@yahoogroups.com...
I did add two schematics to my Album about simlified principle how I have thought to try balancing. If to spinn rotor bell (with magnets) then heavier sector...
I have rewound my 15 tooth 4 pole 45mm stastor lenght motor as well as changed the mafnets. Now I use 56 of curved magnets 31.94mm OD, 27. 94mm ID x 6mm. Rotor...
I have tried a number of ways to get a perfect balance but the magnets seem to have some effect on the end result. Without the magnets in the bell my...
Hello Colleagues, I don't know if this is a good idea or not but it seamed to work for me. On some of my smaller motors I ground a precision angle on each end...
... I think it's a U shape bearing support, with the open end closed with a piezo sensor and physical stop. True will have no extra forces, off balance will...
... I have asked a guy who does a lot of washing-machine repairing and he said that in Europe a brand called "Eudora" used this kind of motor for a long time. ...
hi Arno, Not much adequate things when search Eudora :-( Here you can see 36 tooth motor of this kind type. I would like to get this kind stators ;-) ...
Hi Herbert, ... Their homepage is: http://www.eudorasoba.at/ Seems to be a swiss company wich produces in Austria. Have asked their support by email and they...
... bearings. David, the 5mm or even 10mm larger than the external dia. of the bearings is to allow the shaft/bearings to move inside the tube and as a result...
Hi Arno and Herbert I managed to get this stator and have got some specially designed magnets for it from neodyme Sandra. I've made a low profile annoucement...
hi Peter, Motor or generator - what you are planning? Will it 36 ot 42 tooth one this stator? I like 36 tooth more because you can choice between 2x18/16(or...
Hi Herbert Its 36 tooth but a 48 tooth stator from a 11 KW classical machine as well is under construction. My first attempt on the 36 will be 36T38P because...
ja-jaa, Peter ;-)
Pure LRK it is 3x(12/10) 0r 3x(12/14)
cheme -> AabBCcaABbcCAabBCcaABbcCAabBCcaABbcC then 30 or 42 rotor poles.
It is like three series LRK...
I forgot to add that Plettenberg Predator - 10KW motor - has 24 tooth stator and 20 pole rotor - it is 2 x pure LRK on the one stator. Plettenberg does not use...
Hi Herbert yes all true - and I try to lay my hand on a second one so you might try other combinations. One aspect we willl see is ... what is really the sum...
I am looking for a brushless motor for an under water ROV. A water tight thruster housing is very difficult to construct. Pressure compensation and shaft...
