Problems solved by technology

Since the leakage magnetic path G1 flowing to the inner stator 101 side through the first return magnet part 103b and the second return magnet part 103c is generated in a part of the magnetic circuit G, it is difficult to achieve a further increase in the output power of the reciprocating cycle engine 100. raised questions

Embodiment Construction

[0037] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0038] First, a schematic configuration of a reciprocating cycle engine 10 including an outer stator according to the present embodiment will be described. This reciprocating cycle engine 10 is an engine used in various generators, and has a structure as shown in FIG. 1 . That is, around the annular or columnar inner stator 11 , the cylindrical movable element 13 and the outer stator 12 are arranged coaxially sequentially from the radially inner side to the outer side. That is, the outer peripheral surface of the movable element 13 is opposed to the inner peripheral surface of the outer stator 12 , and the inner peripheral surface of the movable element 13 is opposed to the outer peripheral surface of the inner stator 11 via a metal pipe 15 described later. In other words, the outer stator 12 is arranged around the inner stator 11 leaving a cylindrical space, and a cyl...

Abstract

An outer stator provided in a reciprocating cycle engine along with an inner stator and a mover, having a tubular shape placeable around the mover coaxially with the axis of the mover, and forming a magnetic path between itself and the inner stator via a field magnet section of the mover. The outer stator has an opening formed on that inner peripheral surface side of the outer stator which faces the mover; an inner space opened via the opening and in which a coil is placed; and recesses provided at both ends along the axis when viewed in a cross section including the axis and recessed radially outward from the inner peripheral surface side.

Description

technical field [0001] The invention relates to an outer stator of a reciprocating cycle engine and the reciprocating cycle engine. This application claims priority based on Japanese Patent Application No. 2005-221744 for which it applied in Japan on July 29, 2005, and uses the content here. Background technique [0002] Conventionally, reciprocating cycle engines have been used in drive devices, generators, and the like. As the drive device, for example, a Stirling cycle engine disclosed in Patent Document 1 below is known. [0003] As a reciprocating cycle engine 100 used for a power generator, a structure as shown in FIG. 5 is known. That is, around the annular or columnar inner stator 101, the movable element 103 and the outer stator 102 each formed in a cylindrical shape are coaxially provided. In the outer stator 102, an internal space 102a opened by an opening 102b formed in the inner peripheral surface thereof is formed. A winding coil 104 is arranged in the inner...
