Induction coil arrangement for e.g. shaver, has primary coil winding arranged in middle region of primary-side coil core, where middle region is curved towards secondary-side coil core in charging condition

摘要

The arrangement has a primary-side coil core (30), and a primary coil winding (300) arranged in a middle region of the core. A secondary coil winding is arranged on a secondary-side coil core, which is positioned between primary coil winding-free end regions (32, 33) of the primary-side coil core in a charging condition. The middle region is curved towards the secondary-side coil core, and end region surfaces (34, 35) of the primary-side coil core are turned towards the secondary-side coil core in the charging condition.
