INFLUENCE OF THE NUMBER OF ROTATION WINDING PHASES ON THE STRUCTURE AND PROPERTIES OF ELECTRIC MACHINE WITH THREE DEGREES OF FREEDOM ROTOR

open access: yesTekhnichna Elektrodynamika, 2023
The structure of an electric machine with a rotor, which has three degrees of freedom of rotation (EMTR) and consists of external and internal magnetic circuits, is considered. Between them, in the air gap of a spherical configuration, there is an m-phase rotation winding and a control winding.

Gopakumar-Vafa hierarchies in winding inflation and uplifts

open access: yesJournal of High Energy Physics, 2021
We propose a combined mechanism to realize both winding inflation and de Sitter uplifts. We realize the necessary structure of competing terms in the scalar potential not via tuning the vacuum expectation values of the complex structure moduli, but by a ...

DC current control of a zero-sequence load using a diode rectifier for a three-phase four-wire motor drive system

open access: yesNihon Kikai Gakkai ronbunshu, 2020
This paper describes the active DC current control of a zero-sequence load using a diode rectifier for a three-phase four-wire motor drive system, intended for application to (for example) a three-phase motor with an axial magnetic bearing.
