Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In this paper we consider the synchronization of asynchronous motors in a multi-motor drive system that facilitate synchronous starting of the motors, as well as their synchronous braking, which excludes the preliminary synchronization and synchronous start. The equations of the moments of a multidriving asynchronous electric drive of the coordinated rotation of asymmetrical motor supplies, consisting of the moments of the motors with the forward and reverse direction of rotation of the magnetic field, are given. The form of the mechanical characteristic for asymmetrical feeding of the stator windings of the motors is shown.Thyristor control circuits for preliminary synchronization, synchronous starting and braking, protected by copyright have been developed.Preliminary synchronization, synchronous starting and synchronous braking of the synchronized rotation motors are modeled on the Matlab application package, which confirm the physical basis of the motor operation mode.
