| 简介 |
FIELD : engines.
SUBSTANCE : invention relates to electric motors with reciprocating armature. Motor comprises cylindrical housing 1, inductor (stator) 2, at least two centering supports 3, as well as an anchor, which is installed in housing 1 with possibility of back-and-forth movement along axis of housing. Anchor comprises rod 4, a set of permanent magnets 5, multiple separating rings 6 and multiple cylindrical bushings 7. Rod 4 and ring 6 are made from diamagnetic material. Magnets 5 are made from rare-earth elements with cross magnetisation. Bushings 7 are made of ferromagnetic material. Bushings 7 and rings 6 are arranged on rod 4 with alternation relative to each other so that any two adjacent bushings 7 with their ends facing each other together with inner surface arranged there between separating ring 6 form a capsule, in which is freely associated magnet 5 with orientation of its poles along axis of housing 1. Any two adjacent magnets 5 are fitted with orientation to each other identical poles.
EFFECT : technical result is improved reliability owing to protection of permanent magnets from foreign mechanical effects.
