Gas exchange valve actuator for a valve-controlled internal combustion engine

Valve-controlled internal combustion engine having at least one combustion cylinder, wherein at least one gas exchange valve actuator comprises:

• a rotor (16), which is to be coupled to a valve member (12), and a stator (18), wherein
• the rotor (16) has at least one stack (14, 14′) of superposed permanently magnetic bars (30, 30′), and
• the stator (18) is formed, at least partially, from a soft-magnetic material and has at least one pair of teeth (22a, 22a′;
• 22b, 22b′;
• 22c, 22c′;
• 22d, 22d′;
• 22e, 22e′;
• 22f, 22f′) with mutually opposed teeth (22), of which each pair of teeth receives a stack (14, 14′) between them while forming an air gap (24, 24′) in each case, and wherein
• the stator (18) has at least two magnetically conductive inner regions (50, 50a) which are arranged at a predetermined distance A from one another in the direction of movement B of the rotor (16) and are at least partially surrounded, in each case, by a hollow-cylindrical coil arrangement (60, 60a), the central longitudinal axis M of which is oriented approximately transversely to the direction of movement B of the rotor (16).
