SC_T = Transformer speed controller
SC_E = Electronic speed controller

^** Caution: an electronic controller can produce a magnetic noise

ŋ_t = Maximum total efficiency
Tm = Maximum air temperature
Tu = Maximum ambient temperature
To = Minimum operating temperature
Lwa 2 = Casing sound power level
Lwa 5 = Sound power level @inlet
Lwa 6 = Sound power level @outlet
The sound power levels are measured according to DIN 45635 part 2 & 38
