Steinmetz hysteresis coefficient for steel
網頁2024年8月23日 · Pb = η*Bmaxn*f *V. From the above equation, ‘Pb’ is the hysteresis loss. ‘η’ is the Steinmetz hysteresis coefficient which depends on the material. ‘Bmax’ is the density of highest flux. ‘n’ is the Steinmetz exponent, based on the material it ranges from 1.5- 2.5. ‘f’ is the frequency of the magnetic reversal for each second. http://www.kpubs.org/article/articleMain.kpubs?articleANo=E1EEFQ_2013_v8n6_1409
