Wow! That was easy!
Got the encoder and brake removed. All done in about an hour. It was much easier than I thought it would be.
Splitting the case was hardest, but only because it was the most time consuming. It really wasn't difficult.
I couldn't get the brake coil out, I guess it was a real tight fit. There are 3 bolts in the cover to hold it in place, I expected it to just drop out but it didn't. So, I removed the friction plate and actuator plate but left the coil in place. I can put everything back at a later date if I decide I need it.
If you want to see the innards bvan posted some pictures of a Yaskawa that he took apart. Mine looks identical.

There is some friction from the bearings and of course the mass of the rotor. Hard to explain. There's no flywheel effect so it stops pretty quickly, but it's not hard to turn and there's no cogging except when the outputs are shorted. Then it's almost impossible to turn.
I quickly got out some clip leads, a small rectifier and VOM. I had to play
Got 6 volts just twisting it by hand and 0.8 amps. Yeah, I'm gonna like this
But it's going to take some fairly hefty blades to turn it.
I'll have a bigger rectifier assembled tonight and start some testing with a drill. This is gonna be fun!
