Answer: Only NEMA frame motors.
For IronHorse, only TEFC (Totally Enclosed, Fan Cooled).

Question: What motors can be used with a drive (inverter)?
Answer: IronHorse can be used for straightforward applications, that don't require use below 360 rpm for pumpsor fans, or used below 900 rpm for winders or mixers. IronHorse always requires the use of a reactor (called a load reactor) between the motor and the drive.
