FIELD: electrical engineering; linear- and angular-displacement data converters, stepping motors, direct- and alternating-current machines for various power outputs.
SUBSTANCE: proposed electrical machine stator has core assembled of alternating radial nonmagnetic inserts, ferromagnetic cores, and yokes with windings, every two adjacent ones being differentially connected. Bores for bearing supports are coaxial with core bore. Core is built of U-shaped magnetic circuits whose teeth are facing outside and yokes that join teeth of U-shaped magnetic circuits with opposing teeth of adjacent U-shaped magnetic circuits. Each magnetic circuit has lengthwise disposed slots accommodating nonmagnetic strips to form longitudinal holes and alternating magnetic and nonmagnetic surfaces facing rotor stack assembled of toothed stampings. Butt-ends of nonmagnetic inserts are joined with supports to form electrical machine stator frame.
EFFECT: facilitated manufacture due to simplified configuration of magnetic circuits and yokes.
