Question: What style of motors do we carry?
Answer: Only NEMA frame motors. For IronHorse, only TEFC (Totally Enclosed, Fan Cooled).

Question: What motors can be used with a drive (inverter)?
Answer: Any Marathon motor can be used with a drive. Some may be more than is needed for a particular application. Example: a MicroMax and BlackMax could both come in 1/2 hp in the same frame size. The MicroMax is normally the recommendation for general use ( pump,fan,etc). A more demanding application might be better suited for a BlackMax motor.
