Abstract
An iron core comprising an outer yoke, side poles disposed on both end portions of the outer yoke, and a center pole disposed between the side poles, wherein a magnetic path of polar portions of the center pole is formed as an open-circuit. There can be restricted for short-circuiting of magnetic flux of permanent magnets and thrust of an oscillator disposed at an air gap formed between electromagnets can be improved.

An iron core comprising an outer yoke, side poles disposed on both end portions of the outer yoke, and a center pole disposed between the side poles, wherein the center pole is formed by a pair of magnetic poles which are separated from each other by a specified distance, extension portions in a mutually facing direction are formed at the pair of magnetic poles, and a magnetic path of magnetic pole portions of the center pole is formed as an open-circuit.
An iron core comprising an outer yoke, side poles disposed on both end portions of the outer yoke, and a center pole disposed between the side poles,
- wherein a magnetic path of magnetic pole portions of the center pole is formed as an open-circuit,
- wherein the center pole is formed by a pair of magnetic poles which are separated from each other by a specified distance, and
- wherein an extension member is fitted between said magnetic pole portions.
