well - it is effectively the same thing - but it is for a linear actuator - so each magnet ring has to be equivalent to the radial magnets on a Fisher and Paykel 'smart drive' washing machine motor (bloody fantastic bit of technology those!) - so the solenoid pole facing the armature magnet...

Many thanks for that - it is a great source!- I'll have to trawl a bit through it - yes I know that most engineers may have packages - but i am looking for something 'more immediate' - for getting sketches accross quickly - I notice that they have an electronic CAD that works on...
Hi
Is there an e-mail friendly (feebie as well) drawing package available that will allow quick and simple transmission of sketches and fairly basic drawings (vector) to be attached to e-mails so that they can be treated as text (and hence allow the recipient to change and annotate easily). The...
Hi - thanks for the responses..
Unfortunately conventional toroids won't work -
the magnetic axis has to be radial - which means that a coil that is effectively circumferentially wound, has to be inserted in the toroid-like form. This is what makes things difficult. We've figured out the...
Thanks for the suggestions - the application is for a linear actuator - and it is coaxial. This is why the need for the odd electromagnets. Plain low carbon steel will probably be OK - as it is a low frequency device - but trying to get hold of 3" latheable bars in Australia is a bit of a...
I am trying to design toroidal ring electromagnets (radially magnetised) - but am having considerable problems with finding a suitable core material - pure iron is prohibitively expensive, and the core is something that could be produced easily with powder technology - but I find I am batting...
