Abstract
Устройство трехфазного синхронного двигателя с возбуждением от постоянных магнитов, включающее трехфазный статор из шихтованной тонколистовой электротехнической стали с явно выраженными полюсами в количестве кратном трем, с обмотками статора, намотанными вокруг полюсов статора, и ротор, состоящий из полюсов возбуждения (постоянных магнитов) в количестве кратном двум, устанавливаемых на металлической втулке, выполняющей функции спинок ротора, отличающееся тем, что, с целью повышения эффективности двигателя, втулка ротора выполнена из неферромагнитного материала, используются дополнительные полюса из ферромагнитного материала, устанавливаемые на втулке ротора между полюсами возбуждения, а также тем, что в полюсах возбуждения (постоянных магнитах) в плоскостях, перпендикулярных оси полюсов, установлены несколько тонких пластин из мягкого ферромагнитного материала с высоким значением индукции насыщения (Bs). A device for a three-phase synchronous motor with permanent magnet excitation, including a three-phase stator made of lined sheet steel with three distinct poles, with stator windings wound around the stator poles, and a rotor consisting of a multiple of excitation poles (permanent magnets) two mounted on a metal sleeve that acts as the backs of the rotor, characterized in that, in order to increase engine efficiency, the rotor sleeve is made of of non-ferromagnetic material, additional poles of ferromagnetic material are used, which are installed on the rotor bushing between the excitation poles, as well as the fact that several thin plates of soft ferromagnetic material with a high saturation induction value are installed in the excitation poles (permanent magnets) in planes perpendicular to the pole axis (Bs).
