Hi there!
Recently, I am studying this loss from the following link:
https://www.electricalvolt.com/2019/08/eddy-current-loss-formula/?expand_article=1
Just to summarize an idea,
Supposed that we got a material, which is penetrated by a magnetic flux. The material will generate the eddy current to oppose the change of the flux. We divide this material into portions.
We treat each of the portion as a one-turn coil, having I_eddy flowing through.
Use the Faraday's Law to find the induced voltage (E) in each portion.
Use R = rho*(length)/(area) to find the resistance of each portion (that I_eddy flows through)
The power loss of each portion is dP = E^2/R
Integrate dP over all the portions to get "P: The power loss due to eddy current."
From this equation in the link, I am curious why the bounds of the integration is 0 to T/2. Should it be -T/2 to +T/2 instead?
(Please look at the diagram in the aformentioned link)
Best Regards,
BlackMelon
