This is a pump motor, so my guess is that it's series-wound.

Probably didn't have speed control, just on/off, so, I can't see why Sep-Ex would make sense.

Kinda small for an EV. It's only rated for 3400 watts continuous.

Are you saying that it seems to be a DC series-wound motor?
Is "DC Series-Wound" & "DC Separately Excited" motors are the same?
Can both be used for Regenerative feature?

No. They have the same type of rotor (armature) winding, commutator, and brushes; however, the field winding of a series-wound motor is in series with the rotor winding (so the same current goes through both), while the field winding of a separately-excited motor is in parallel with the rotor winding, so the current in it is unrelated to rotor current.

Can both be used for Regenerative feature?
A separate field winding allows control of the motor in generator mode for regenerative braking. Generally, it is not feasible to control a series-wound motor for regeneration.
