OK In the armature windings the phase difference between Cemf and Vt is 180 degrees. How does the storage capacity of a capacitor compare to that of a battery? I have seem some work on this and I will research.. Thanks again. John

I'm not to anxious to throw this energy away, as with braking. I would like to catch it and put it back in the batteries or a fly wheel or pump water up on the roof. I also want to stay with this series DC motor for starting torque reasons. The theory I'm having trouble with is the downhill...

Great.. So far this is good. Please help me through this. " if the shaft speed exceeds its rated speed," If I'm coasting down hill and reduce the voltage to the motor would this cause it to generate? Also is there a problem with brush location when this happens? "It depends on...

Question. If I'm using a series dc motor to move my car, will it turn into a generator when the car is going down hill? And which way will the current flow ? The same way as when it was a motor? I would apply a load other than trying to charge the batteries directly. Thanks in advance...

Thanks jbartos, I have searched Thomas Register and all I find are self excited and permanent magnet. I was hoping you guys might have seen one or am I dreaming? But I'm still looking. THANKS again. John

I'm tring to find a 1 to 2 HP 3 phase generator/alternator that has slip rings for variable output. Like an automobile alternator with out the diodes. 100+ volts, All I can find is brushless. Any help will be apprecieated. Thanks John
