Abstract (en)
[origin: EP0603629A2] The electromagnetic arrangement has an electric coil (1) whose core (2) is constructed as a split pole. In order to generate a phase shift, one pole (5) of the split pole is surrounded by a shading ring (7). An armature (4) is arranged opposite the split pole. A yoke (3) which closes the magnetic circuit is also provided. A step is provided in the shaded pole (5), specifically in the region between the shading ring (7) and armature (4), in order to increase the retention force between the coil core (2) and armature (4). This leads to an increase in the magnetic flux density and thus in the magnetic force. <IMAGE>
