METHOD FOR MAGNETISING ROTOR OF ELECTRICAL MACHINE, MAGNETISING SYSTEM FOR ROTOR OF ELECTRICAL MACHINE AND METHOD FOR MANUFACTURING ROTOR OF ELECTRICAL MACHINE Russian patent published in 2015 - IPC H01F13/00 H02K15/03 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering, to electrical machines. The method includes assembling an array of non-magnetised anisotropic segments of permanent magnet around a spindle of the rotor enclosed into a metal ring. Then optimal magnetising directions are defined for the above segments, the assembled segments are positioned around the rotor spindle so that optimal magnetising directions for anisotropic segments of a permanent magnet are aligned in direction of magnet flux lines generated by a magnetiser. Excitation of the magnetiser for the purpose of segments magnetising is made by direct-current pulse during optimal pulse duration, which depends on thickness, magnetic permeability and specific electrical resistance of the locking ring.

EFFECT: simplified magnetising.
