Abstract
A high-power ignition coil for internal-combustion engines has a soft-magnetic layered core (8) of grain-oriented lamination and an air gap ( DELTA ) and a primary and secondary winding (2, 3) surrounding the main core (4). In order to achieve an unchanged energy storage capability and unchanged performance data for the ignition coil, without having to provide a permanent magnet, the core (8) is designed and constructed such that the main flux (0H) in the main core (4) generated by the primary winding (2) runs in the preferred direction of the grain-oriented lamination and such that the magnetic induction in the yoke parts (9, 10) of the core (8) is reduced such that an approximately equally large magnetisation requirement results in all the partial sections (4, 9, 10, 11, 12) of the magnetic circuit. <IMAGE>
