Re: GE Motor

[stevenr@flash.net]

Hello Henry and everyone,

Actually I didn't make compensation windings, I just wanted to add them if I 
could get them from GE.  I'm adding a winding for Regen use.  The GE motor
has lots of room inside and I thought mabey I could use the compensation 
winding for regen.  But they proably wouldn't work anyway since they are out of 
phase with the brush timing.  I'm going to add a winding around the existing 
field coil using smaller wire that I can enerjize with a seperate regen circuit.
I have no idea how much energy I need to make a decent amount of regen current.
but I guess I will find out when I get the motor casing back from the motor 
shop.
