    • The invention relates to an electric machine (1, 15, 17, 25, 26), comprising a magnetically supported reluctance rotor (2) and a stator (4) that forms poles (19, 20, 21, 22), which stator has at least one electrical stator winding (5) for producing an electromagnetic control flux (6') and at least one permanent magnet (7, 7', 7'', 7''', 8, 8', 8'', 8''') for producing a permanent magnet flux (9'), wherein the electric machine (1, 15, 17, 25, 26) has electromagnetic and permanent magnet circuits (6, 9), which are superposed at least in partial regions of the gap (3) depending on the rotor angle in order to form torque (M) and/or radial load-bearing capacity (F1, F2). In order to enable advantageous properties, according to the invention, when the magnetic circuits (6, 9) are considered separately, a substantial part of at least one magnetic flux (6' and/or 9') within a permanently magnetic pole formation (10) having equal polarity, within an electromagnetic pole formation (18) having equal polarity, or within a continuous and winding-free, in particular ferromagnetic, stator sector (16) closes across the gap (3) and across the reluctance rotor (2) to form a magnetic circuit (6 and/or 9) at least at one rotor angle.
    • 有一个电机(1,15,17,25,26)配有一个磁性地安装磁阻转子(2),并用一个极(19,20,21,22)形成定子(4)中示出的至少(一个定子电绕组 5),用于生成 '用于产生永久磁通(9)' 的电磁控制通量(6 ')和至少一个永磁体(7,7',7”,7" ”,8,8' ,8”,8" ) 其中,所述电机(1,15,17,25,26)的电磁和永久磁电路(6,9),该转子角依赖于局部区域的扭矩(M)和/或径向悬浮力(F1,F2)至少 的空气间隙重叠(3)。 为了使有益性能,建议的是,当单独考虑,磁性电路(6,9)具有永久磁性,同极性磁极结构内的转子角度的至少一个磁通量的很大一部分(6“和/或9”),其具有至少 (10),包括电磁,极性相同极结构(18)内或在连续的和无绕组,特别是铁磁定子区段(16)内,穿过气隙(3)和所述磁阻转子(2)(于磁性电路6和 /或9)关闭。
