Thats what I would expect with a four pole armature. With a 2 pole armature you have more room. Lap wound armatures will operate with as many poles as you want but if you look at the windings you see that they appear to be 60 to 90 degree poles. BEMF in the powered field coil is inevitable with these windings so a higher input voltage will be required. The best armature appears to be simple wound 2 pole.hiwater wrote:On stock armatures coil A needs to be pretty close to coil D. But not touching. This produces the most voltage.
If I understand you correctly, the answer is yes.hiwater wrote:Where as the rewound ones has 2 more armature slots for exposure to the field poles. That's why it looks like coil A is at 90 degrees to the armature. That would be the center of the armature then. Help with motoring and charging. So it has to me moved slightly one way or the other to compensate for what we want it to do.
Brushes can be moved some to aid in generating or motoring effects also.
