Sorry, you're way off base. There is nothing mysterious about a series wound motor. The important thing is the field current equal the armature current. The ratio of armature voltage to field voltage depends on load and speed but for a ball park use 100 to 3.I know that a series has a different power distribution, wire gauge, and wire length than a sepex.
I want a battery pack voltage total of 120-144v
So I could make a total of 144v by splitting the total into a 60v pack, routed to a controller for the field, and a 84v pack to a controller routed to the armature. I would like to be able to connect the packs into the total pack.
Splitting the total based on the theoretical, mysterious, voltage sharing of a series motor.
Right? I hope...
If this works, I have another theory![]()
I have seen a case or two where for unusual reasons it has been done. It takes a thorough understanding of the series motor and design of two unique pwm controllers with a common control.
If for some reason you're set on the idea, study up on DC motor theory and control.
