INDUCER OF LINEAR ELECTROMAGNETIC GENERATOR WITH EXCITATION MAINLY FROM PERMANENT MAGNETS Russian patent published in 2017 - IPC H02K35/02 H02K1/06 

FIELD: machine building.

SUBSTANCE: invention relates to the electrical machine building, in particular to linear inducers of magnetoelectric generators with excitation from permanent magnets. Inducer comprises mounted on the support assembly a circular magnetic insert made from a group of separate circular monolithic magnetic sections with radial magnetization and in pairs alternating polarity (NN-SS) in the circumferential direction. Support assembly includes arranged coaxially with circular magnetic insert a cylindrical metal casing of the magnetic core made of a ferromagnetic material. Inner side wall of each separate circular monolithic magnetic sections of the circular magnetic insert is formed of N-pairs of located diametrically opposite to each other uniformly along the circle arc and symmetrically relative to the central axis of the circular magnetic insert cylindrical surfaces of revolution crossing each other and forming beak-shaped ones at the crossing sections.

EFFECT: technical result is the increase of magnetic induction, total magnetic flux and efficiency of the inducer, higher reliability.
