Homework Statement
The aim is to optimize this actuator to get the maximum force from it. Here is the circuit diagram below:
Homework Equations
The Attempt at a Solution
Length of air gap top (Ragt in diagram) = 0.5 mm
Length of air gap centre (Ragc) = 0.25 mm
Current in coil = 0.8 A (I calculated it), current in coil must be less than 1A
I'm not going to put too many calculations here because it might be too long and people reading it will get a headache, but anyway I have some questions
Will the flux divide equally ?, my guess is no because the air gap reluctance's are different
To get the drop in RcoreBCDA, I use F = Hl, now my question is will the mean path length(l) run from ABCD ?
Lastly, any guidelines on how to solve for the magnetic fluxes and mmf drops ?, I did attempt it but not sure it it's correct
Any help will be greatly appreciated, this my design project and it's due very soon
