ELECTRIC MACHINE HAVING A MAGNETICALLY SUPPORTED RELUCTANCE ROTOR

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.
