Rich and Andre are both correct. ADC can build this motor as either a sep-ex or series motor quite easily just by changing the size of the field winding. Almost all traction motors are 4 terminal and the operation is really decided by winding size and external connection. My point is that for high voltage EV operation you really need interpoles. They have built both sep-ex and series motors in this frame size for customers, but none have been built with interpoles. Rod
I am not meaning to step on anyone's toes here but every ADC motor I have seen was a sep-ex motor. But all of them were externally wired as a series motor. They likely have made other kinds but I have not seen them. A true series motor would only have 2 terminals, the armature and the field would be connected inside the motor. I believe what Rich and Rod are really discussing is weather the field is a low voltage high current winding or a high voltage low current winding. If both ends of the armature and the field are brought to the outside of the motor it can be used as a sep-ex motor. Andre' B. [EMAIL PROTECTED] If something cannot be defined, it does not exist.

A good friend of mine heads up the controller division for their parent company, Kinetek (Imperial Motors, ADC etc). He might know if they plan on doing a sepex version.

I have heard that it is some form of Sep-ex. If you can Actually say for certain that it is a Series, I would be Greatfull. Like have you seen it, and do we have motor curves for it???
