The invention is a micro-consumption reciprocator, provided with coil, the framework of the coils holds an annular soft iron core, there are permanent magnets arranged on two ends of the soft iron core, the
magnet poles are opposite and connected by a post, and top structural plate and parallel are installed on two ends and fixed by bolts; as it applies a
pulse current on the coil, the generated polarities and the polarities of the permanent magnets form the condition that the same polarities are mutually repulsive and the different polarities are mutually attractive and then bring about
reciprocating motion, and it does not use the current to maintain the work, and can not make the coil heated and burnt, realizing the advantages of high
electricity saving, reliable action, stability, simplicity, no
noise, etc; it is used in electromagnetic valves, relays, breakers, protectors, contactors, and other switch products to form various series of independent products widely applied in industry,
agriculture, national defence and
spaceflight&
aviation. It is used in lock products, able to interface with
monitoring system and intelligentize, and able to be widely applied to civil houses, automobiles,
housing estate management and safety departments.
