Technical scheme of the present invention is: a kind of permanent magnet linear generator, and it comprises stator and mover; It is characterized in that stator is comprised of permanent magnet and mover yoke section, this mover yoke section top and below on all be stained with permanent magnet; Mover is comprised of mover iron core and coil, and this coil is embedded in the wire casing of mover iron core; Described mover has two, is arranged symmetrically in respectively on the upper side and downside of stator; Described mover iron core is comprised of the mover punching, has the wedge type groove that passes for pull bar in the mover punching, and pull bar is connected with cover plate and casing by securing member, and realization is arranged in being located by connecting of mover on stator upper side and the downside and cover plate, casing respectively.
The further technical scheme that has additional technical feature on the basis of technique scheme is:
Described permanent magnet linear generator, its cover plate links to each other with bearing by the support of bearing; In the mover yoke section guide rail is installed, this guide rail is used for and bearing fit is realized relative motion between stator and the mover.
Described permanent magnet linear generator is provided with between its casing and the cover plate for the gap length of regulating between two movers and regulates pad.
Be provided with the identical gap balance adjustment pad in gap for the mover of the gap of regulating the mover on stator upper side and this upper side and stator downside and this downside between the described permanent magnet linear generator, its support of bearing and cover plate.
Described permanent magnet linear generator, its casing also have gusset to be welded by riser and base plate.
Principle of the present invention and significant technique effect are described as follows:
Two movers of the present invention are arranged symmetrically in respectively the upper and lower sides of stator, consist of two same motor and are arranged symmetrically with casing; Be provided with multiple adjusting pad between casing and the cover plate, can regulate arbitrarily the gap between two movers; Cover plate links to each other with bearing by the support of bearing, bearing and be installed in guide rail in the mover yoke section and realize relative motion between stator and the mover; Be provided with multiple adjusting pad between the support of bearing and the cover plate, can regulate arbitrarily on stator and the upper side and downside on mover between the gap, realize that inner two motor gaps are identical.
Compare with conventional linear electric generator, the present invention reduces by half power density increase, the bearing of linear electric generator, stator in theory stressed making a concerted effort be zero, solve the stressed problem of bearing, be that shaft strength is zero with joint efforts in theory, also have, the adjustment air gap succinctly makes things convenient for, frictional dissipation is little, and linear electric generator structure technology design problem is solved preferably; Complete machine structure of the present invention is succinct, firm, reliable, and particularly: according to the technical scheme of the present invention's two motor symmetrical structures, also one-tenth four motors capable of being combined or six motor symmetrical structures become electric efficiency and require higher permanent magnet linear generator product.
