Abstract
The invention presents a magnet system (10) for electromagnetic converters, which is essentially formed of two parts. This magnet system (10) is formed of a one-piece pot-shaped yoke (11), which contains a bottom (13), an edge wall (14) and a core (16), and a permanent magnet (12). This permanent magnet (12), which is either connected to the core (16) or the edge wall (14), is magnetized crosswise to the extended direction of the core axis. This type of configuration permits to construct a very low scatter magnet system (10), whose number of components is clearly reduced with respect to known systems. The connection of yoke (11) and permanent magnet (12) is advantageously made into a press fit connection.
