Electromagnet back emf (CEMF), need advice
Holding force 500lb
The input is 24v, . once the voltage is disconnected the Back EMF will occur, at that instant there still is a magnetic field which collapses very fast, in collapsing it 'cuts' the coil at high speed and the higher the 'Q' coil the more voltage is 'generated'. I imagine that my electromagnet that can lift 500lb with 24v will generate a huge CEMF.
So my question is, approximately how much Cemf should I expect and could I use it to recharge my batteries? Let's say I switch it on for 1sec than switch it off.
There are techniques for back emf suppression,
I would like to redirect it, transform it to make it usable and recharge my batteries with it. If I manage to do it, will I get at least as much power from the cemf in order to be able to recharge my batteries (or capacitator)
