MAGNETO-ELECTRIC MACHINE OF LINEAR TYPE

摘要

The invention claimed here refers to electrical engineering and may be used to convert mechanical energy of reciprocating motion to electrical energy and vice versa. The machine has a stator with windings and a moving body installed in such a way that a possibility of reciprocating motion is provided. The stator has at least one magnetic part, each of which has at least one permanent magnet and has at least three unidirectional projections that form magnetic poles of alternating polarity. The cavities are formed between the projections, with stator windings placed in said cavities. The moving body has at least one part made of magnetically soft material. The stator and the moving body are positioned so that the moving body part made of magnetically soft material, in the course of the motion of the moving is (at least partially) within the magnetic fields of the poles of the magnetic part of the stator. The invention may be used for the creation of linear electric machines characterized by high dynamic characteristics, high efficiency and low weight and size.
