when i look up AF 22 on eshop there is something interesting. 3HP, 3ph moves same amount of air as 4HP, 1ph unit. anyone know if these specifications are correct?

i am interested in understanding if 3ph motor has advantage over 1ph. this might be a good example possibly showing (or not) that the higher torque of 3ph can do more actual work under load than a 1ph motor both pulling same current.

imran?
