Calculate toroid winding to depolarize magnetization?
« on: June 23, 2010, 09:42:05 AM »
I am building an e-Orbo motor and want to make sure I get the number of windings and wire gauge correct to depolarize the magnetization of the toroid when the magnet reaches its peak of attraction to it - with the minimal amount of current.

I have found many toroid winding calculators but none to calculate depolarization.

Does anyone know how to do this?

See this post for the method:

However, the core behaves differently in presence of a magnet.

About the AWG, take the thickest possible wire but not so thick that it blocks the hole of toroid for given number of turns.

Awesome! Thanks :)
