Induction power loss temperature
Induction heating allows the targeted heating of an applicable item for applications including surface hardening, melting, brazing and soldering, and heating to fit. Due to their ferromagnetic nature, iron and its alloys respond best to induction heating. Eddy currents can, however, be generated in any conductor, and magnetic hysteresis can occur in any magnetic material. Inducti… Web1 mrt. 2024 · The importance of stray load losses in induction machines was illustrated, indicating that a small improvement of the efficiency would mean about five times reduction in the losses of the input power. ... By keeping the working temperature of the magnets low, higher power density can be achieved [21].
