Kone Elevator Drive / Teardown, IGBT test, failure analysis
« on: October 16, 2018, 08:48:54 AM »
Posted a link to this on EEVBlog forum, forgot to post it here too.

Found this video from Kevin Gittemeier
Yes the magic smoke did escape, from several places.
Rather interesting how cheaply made an elevator drive VFD can be.

I also did a teardown of a Kone elevator VFD and it seems to be the exact same unit, except mine was older.

Technological advances especially in the silicon / integrated 3 phase IGBT bricks made all these "small" drives very cheap to produce, there is no longer any real expensive parts to hold back a design or race it to the sky in price, at least not for consumer products, which a small elevator falls under in my view.
