This is a bit embaressing. Sigh..its been a looong time since I needed to figure this sort of thing out.....Im a board changer/wrench turner/relay and plc type...
I have an elderly electromagnetic chuck that Ive been sitting on for a couple years until I found a decent usable 6x8 surface grinder..which I recently did (Covel), but it has no power supply. Rated 110vts DC.
So I dug out a bridge rectifier, added a power cord, and powered up the chuck with the output. Chuck does indeed work, but its a smidge weaker than I think it should be..or would like it to be. Its half wave DC..so Im only applying a magnetic field half the time, right?
Now if I added a simple capacitor to the output, it should give me a longer signal time as it fills in the gaps. This should result in a slightly stronger effective magnetic field. Right? One that is not forming and collapsing 60 times a second
Assuming Ive not shit in my messkit at this point..what MFD cap should I use? Cringe.....blush
Current draw is about 1 amp
Clean DC would be nice..but its only a magnetic chuck....
Now the last thing....some electo chucks tend to magnitize over time..or bleed off the field over a number of seconds.
If I put a maintained On/off/Momentary On toggle switch in...I should be able to run a momentary bit of 110vAC though the chuck to demagnitize it, right?
