摘要：

Rotational energy losses Wr have been measured as a function of magnetizing frequency fm and working induction Bm in non-oriented SiFe laminations and compared with losses in alternating fields Wa. Wr and Wa exhibit a same non-linear dependence on fm, while the ratio Wr/Wa is a monotonically decreasing function of Bm. A phenomenological approach to the behavior of hysteresis and excess rotational loss components is discussed. © 1990.
