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 **** 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....

Shrug..

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?

Thanks

Gunner, hanging his head in shame...
