PCT No. PCT/EP90/00302 Sec. 371 Date Apr. 17, 1992 Sec. 102(e) Date Apr. 17, 1992 PCT Filed Feb. 15, 1991 PCT Pub. No. WO92/07411 PCT Pub. Date Apr. 30, 1992.In a stator-excited synchronous machine with laminated sector stator elements (SS1 or SS2), which are arranged one behind another at an axial distance and are winding-excited by in each case one excitation winding part (EW1 or EW2) of opposite polarity, the operating efficiency can be increased with low outlay when a permanent magnet arrangement (M) having a magnetization opposing the winding excitation in the sector stator elements is provided in the axial spacing chamber between the sector stator elements (SS1 or SS2); in order to lock the position of the magnet arrangement (M), the facing laminations of the magnet arrangement (M) have bent-away tongues (Z) gripping radially from below.
