Air Purification Ec Centrifugal Fans 190mm 220mm 225mm Pa66 Eqjipment Cooling AC vs. EC 1. AC motors are designed to operate at a certain point on their performance curve which coincides with their peak efficiency. Either side of this operating point, the efficiency can drop off considerably. EC motors on the other hand have an almost flat efficiency curve which varies relatively little across the speed range, a range which is not limited by synchronous speeds or as
