The invention relates to an electrical drive comprising stationary outer and inner stators (5, 6; 11, 11a) and a rotatably mounted rotor. Said drive is provided with a plurality of permanent magnet elements (14, 34, 54) for generating an energizing flow and at least one electrical field coil (12, 15, 32). The rotor is provided with at least one pot-shaped element (8, 28, 38, 58) which has a cylindrical wall (8a, 28a, 38a, 58a) and a base wall (8b, 28b, 38b, 58b), said base wall (8b, 28b, 38b, 58b) being arranged perpendicularly and the cylindrical wall (8a, 28a, 38a, 58a) being arranged coaxially in relation to the axis of the rotor shaft (1, 39, W). The base wall (8b, 28b, 38b, 58b) is linked with the rotor shaft (1, 39, W) for transmitting a torque. The permanent magnet elements (14) rest against the inside of the cylindrical wall (8a, 28a, 38a, 58a) and are fastened side by side on the rotor of the drive in the peripheral direction. The permanent magnets (14, 34, 54), together with the outer and the inner stator (5, 6; 11, 11a), form magnetic circuits which completely extend through the cylindrical part of the rotor in the radial direction.

The invention relates to an electromagnetic actuator which actuates a gas exchange valve. Said actuator comprises two electromagnets and an armature which is actuated by the latter and acts upon the gas exchange valve and comprises two spring forces which act in opposing directions upon the armature. The electromagnets have a transformation ratio i = 11/12 of less than 1. The armature and the poles of the electromagnet which are assigned thereto are configured in such a way that the transformation ratio i1 of the contact magnet is greater than the transformation ratio i2 of the break magnet.

The invention relates to an electromagnetic regulating device, in which the windings are subdivided into two partial windings and one of said windings is a rapid excitation winding with low time constants. Said winding is used during the displacement phase for supplying energy and for holding the armature in the end positions, whereas the rapid excitation winding is used for rapidly correcting the armature energy.

The invention relates to an electric segment motor (01) for producing a swiveling movement, comprising a stationary stator (11, 12) and a swivel-mounted rotor (03). Said stator (11, 12) has at least on magnetic circuit (10) excited by at least one electrical exciting coil (13), and at least two permanent magnet elements (08) are fastened to a wall section (09) of the rotor (03), this wall section having the shape, in particular, of a segment of a circle. The rotor (03) is made of a base material (19), and the permanent magnet elements (08) are embedded or molded into the base material (19).

The invention relates to an electromagnetic or electrohydraulic valve control device. According to the invention, a sealed chamber (2) is formed above the cylinder head, and the actuators, which are mounted on supports, of at least one part of the inlet and outlet valves are accommodated in said chamber that is sealed from the outside by a cover (11). The cover is at least partially flown around by a coolant having a lower temperature than engine oil or engine cooling water, e.g. by the intake air of the intake tube.
