I am currently designing a three phase permanent magnet axial flux generator, but have a question regarding the voltage induced in the copper coils. Faraday's law defines this voltage as the number of turns in the coil, times the change in flux (external magnetic field times area of coil) over...

That's not an option unfortunately, i should have mentioned that it's a window ment for a roof angled 45 degrees.

Such a window has already been produced by the company. Our lecturers want us to come up with a completely new design, not currently used by the company, therefore leaving out the simpler or more obvious mechanisms.

The axle which the window rotates about will actually be geared 1:2, meaning the pulley with varying radius will turn 90 degrees, from a fully open to fylly closed position of the window (window opens 45 degrees).

I hope these sketches illustrate the concept better:

I have been struggling with this problem for a long time now, and are hoping you can help me. The assignment was to design a mechanism for opening a window with less effort. My way of solving this is to store energy in a spiral torsional spring as the window closes, which would be released when...
