PDF-DemagnetIsation of permanent magnets in electrical machines

181 samiruohotkkfi Abstract This paper describes how an electrical engineer should take into account the possibility of Permanent Magnet PM demagnetisation when designing a PM machine Different. The Demagnetisation Curve and its Parameters In hard magnetic materials the second quadrant of hysteresis is most important and is called demagnetization curve Demagnetization curves as well as the other quadrants o By .
