In this case, the maximum winding temperature is 155° C (per insulation class F), and the allowable temperature rise is 80° C (per insulation class B). Adding 80° C to the ambient temperature of 40° C, plus the 10° C hotspot margin of insulation class F, gives a maximum temperature of 130° C, rather than the 155° C of a typical insulation class F motor. This means that the “F/B” motor has an additional 25° C safety margin, which can provide significantly longer insulation life (and, therefore, motor life).

Det lär ju vara precis detta som menas, tack för hjälpen!
