Abstract
A method is for the manufacture of an electromagnetic actuator, e.g., for the actuation of a charge cycle valve of an internal combustion engine. The actuator includes a rotary armature movable back and forth by electromagnets and supported in an actuator frame The electromagnets are first inserted loosely into the actuator frame and then brought into a defined spatial position in relation to the rotary armature by passing a current through the magnet. Next, the electromagnets are fixed in the actuator frame, corresponding to selected operating positions. The electromagnet may be provided with studs, which protrude through openings in the actuator frame into the outer chamber of the actuator and at which the electromagnet is connected to the actuator frame, for example, by laser beam welding.
