CONCLUSIONWhere,as it is common practice to set off-diagonal terms in 111 the permeability tensor to zero, experimental data and analysis have been presented that justify this assumption. Moreover, [21 important information on the transverse characteristics of the three most common permanent magnets will help to improve [31 field computation. The values of p i for Alnico 5 and 5-7 are particularly high compared to ph, as was the case for recoil permeability, and this would tend to enhance transverse flux in a magnet that directly experiences armature reaction in an [SI electrical machine. If an exact model of a permanent magnet is required, then the rotation of M0 is found using (15) [ 6 ] or (20 Bull., vol. 7, 1966. pp. 145-149, 1973. 122, pp. 1377-1381,1975. MAG-14, pp. 359-361,1978.The Measurements are carried out on samples in a stress-relieved state and with magnetic anisotropies induced by stress or field annealing. At f = 50 Hz, a minimum in PT versus u is observed. The U-value (urnin) corresponding to the minimum PT increases with increasing IK, I . At f = 400 Hz, a minimum in PT versus u is observed in the samples with indliced magnetic anisotropy, whereas amin = 0 in the stress-relieved samples. However, no correlation between umin and K , is possible from the present data.0 in amorphous (C0o.seFe,.ll)72Mo3Si15Bl0 (A, > 0) and CO,~MO,
