Abstract
In stationary magnetic frequency multipliers which comprise a polyphase primary winding distributed in slots and a secondary winding magnetically coupled to the former, a travelling field can be produced if the primary and secondary windings, designed as ring windings, are arranged in two opposite rows of slots of an iron member with which a return member is so closely associated as to rest isolated against the tooth ends of the latter. In order that at least the primary winding neet not extend over at least two full pole pitches, laminated connecting parts are provided outside of the wound zone of the respective slotted iron member. These connecting parts establish a magnetic connection between the slotted iron member and the return member and are designed so that they remain unsaturated in any operating state.
