CapitanVeshdokiHello everyone! I try not to miss my train, so this log gonna be short. : )
Just want to write a little about experience I had with magnetic locks, which I bought yesterday:
First of all, their efficiency isn't that great as I expected, for example, 60kg of pulling force doesn't mean, that they make field equivalent to a 60kg permanent magnet, because distribution of magnetic lines is different, so in stock (with 4W of power) they cannot mimic rare-earth ones, however, with this setup I pumped in around 300W of power, and it was enough. Now I know, that it's a working concept.However, if we talk about traditional way of powering electromagnets up, 300W of heat dissipation underlies there and it's a crazy amount of heat! In other words, even if we forget about power consumption, we have no way of making so energy-dense electromagnets without that interesting control board, which (hooray!) I already developed and have on my hands.
And it looks like I found a reason, why efficiency changes so much through changing of PSU voltage, there was one stupid mistake I made, I would write a long log on this subject, it should break previous 75% efficiency barrier , )
