Abstract

UA: У статті розглянуто математична модель електропривода на базі лінійного електродвигуна з урахуванням магнітних втрат, а також з метою його подальшого використання у якості основного інструменту при дослідженні на математичній моделі режимів роботи в стрілочному переводі.

EN: The article considers mathematical model of electric drive work based on a linear motor. Linear motors are electric induction motors that produce motion in a straight line rather than rotational motion. They are now used in all sorts of machines that require linear (as opposed to rotational) motion, including overhead traveling cranes and beltless conveyors for moving sheet metal. They are probably best known as the source of motive power in the latest generation of high-speed magnetic levitation trains, which promise safe travel at very high speeds but are expensive and incompatible with existing railroads. Many designs have been put forward for linear motors, falling into two major categories, low-acceleration and high-acceleration linear motors. Low-acceleration linear motors are suitable for maglev trains and other ground-based transportation applications. High-acceleration linear motors are normally rather short, and are designed to accelerate an object to a very high speed. The mathematical description of linear electromechanical transducer is derived from the Lagrange equations.
