THE LAW OF ELECTROMAGNETIC FORCE
Journal Title: Електротехніка і Електромеханіка - Year 2014, Vol 0, Issue 3
Abstract
Calculation peculiarities for Lorentz force, Ampere force, interaction of parallel electric currents, and the moment of electrical machines are analyzed. They have exceptions on application, and they are the rules which result from the law of electromagnetic force as coordinate derivative of the operating magnetic flow. An addition to the direction of electromagnetic force action is proposed. Standards of salient-pole electrical machine designing are considered.
