WebSep 10, 2009 · On the shunt/sepex debate, I'll throw my hat in the ring and say that sepex is a control sheme, not a motor type. A motor may be designed to suit sepex control (eg: low voltage field winding) but it's still a shunt wound motor. Technically, the regen scheme on a series wound motor is a form of sepex also.
