The study of the Sommerfeld effect of the passage of synchronous machine through resonance.

Gennady Leonov

This study was stimulated by the work [1], where in the
neighborhoodof resonance it was observed a "hanging" of oscillation frequency
of an electromotor on elastic platform. This "hanging" is realized
in the form of random oscillations [1] and is often called a
Sommerfeld effect [1--7].
