PM motor with field winding

JT your explanation makes sense- if a magnet was capable of carrying any more flux it would probably already be magnetized to that level. That's what...

Yes- I'm a man of many projects, and master of none Tell you what I'm doing right now- cleaning out my garden shed so I can put my fiberglass storage...

Anybody ever heard of this? I woke up this morning with this idea on my mind. You have a permanent magnet motor, but you augment the magnetic field with...

Pretty sure a power hacksaw blade is thicker and wider than you might find in a roll. I like the idea though. I don't have a power hacksaw, but I do have...

16 spindles- is that it?

Have fun working with g/s. I hope he learns a lot from you- but not about driving, apparently-

Assuming the blade is one inch wide and .1 inch thick, those figures would mean about 2500 lbs of tension or more- seems pretty high to me. If you're...

I don't know about any of those treatments, but I have considered making myself a custom chair for use in the shop. That would leave me mostly standing,...

I've removed my compound and made a more solid mount for the tool holder. Made a big difference. When I need to turn a taper I can still mount the compound....

Knowing that steel ribbon can be made superior in magnetic properties if it's rapidly cooled makes me wonder about other materials too. I can just let...

Don't you just use the brush tool?

Isn't that what Photoshop is for?

Had mixed emotions watching that. The moment he held the headstock so you could see inside- yikes, plastic gears- and they don't even look good for plastic....

If you don't find bushings, just make a shell from aluminum. As said, all it needs is lube.

Any metal, when you wrap it will spring back...

[darryl]

This is just another idea- if boring isn't going to work out for you, then why not JB the bushings in? Use the alignment setup you have going on now,...

I need to read it again. There was an explanation that seemed right....

[darryl]

I did what turned out to be some pretty heady reading on gyro compasses. It identified pretty much every issue that besets the making of it, and the terrestrial,...

And there it is. I wrapped 270 turns in total, 135 per winding. That's 27 on my counter- 5 rotations per count. I had to leave out one E upon reassembly...

[darryl]

Which is what I'm doing right now. I chose a transformer which does not have weld beads across the laminations, took it apart all the way, removed all...

Standard schottkys are rated at what- 45 volts- if your input voltage is not going to exceed about 40 volts tops, you could be ok with that. Using inductive...
