FIELD: electrical engineering; specific electrical machines for off-line power supplies.
SUBSTANCE: proposed self-excited induction generator designed for operation under abnormal environmental conditions and in hermetically sealed power-generating units has squirrel-cage rotor and core-shaped stator with Z teeth whose slots receive stator winding, as well as field capacitors; novelty is that stator winding is made in the form of Z bars closed on one end by means of end ring. Generator also has additional magnetic core with slots receiving three-phase winding and conducting bars connected on one end with Z bars of stator winding and on other end they are closed by means of other end ring to form Z-phase winding.
EFFECT: enhanced reliability, reduced mass and size of induction generator.
