REVERSIBLE ELECTRIC MACHINE OF RECIPROCAL MOTION Russian patent published in 2013 - IPC H02K35/02 H02K33/16 

FIELD: electricity.

SUBSTANCE: reversible electric machine of reciprocal motion comprises a stator with a coil and an anchor, in which ledges of magnetic conductor poles in initial condition are pairwise arranged oppositely to each other. In each of the specified pairs one of poles is divided into two parts by means of a permanent magnet, which partially forms a pole ledge, and a magnetisation vector of which is co-directed with anchor motion. At the same time the length of the pole ledge divided by the permanent magnet is determined in accordance with the formula: Lmd ≥ Lnm + 2Am, where: Lmd - length of the pole ledge divided by the magnet; Am - maximum amplitude of reciprocal motion of the anchor; Lnm ≥ 2Am - Lm - length of the pole ledge with no magnet; Lm - length of the permanent magnet within the pole ledge.

EFFECT: simplified design with higher reliability, improved usage of magnetic properties of a magnetic conductor and reduced weight and dimension parameters of an electric machine.
