Linear Induction Motor LIM is an asynchronous motor, working on the same principle an Induction Motor works, but is designed to produce the rectilinear motion, unlike the rotary movement produced by a motor; hence the word Linear Induction Motor. LIM is an advanced version of rotary induction motor which gives a linear translational motion instead of the rotational motion. In this type of motor, the stator and rotor are called primary and secondary respectively.

In the electrical systems, we use either in industries, power stations or domestic needs, motors and generators have become a common thing. With the demand for high energy efficient and less power consuming systems, the invention of new models of these electrical devices is seen. The basic calculating factor for motors and generators reliable operation is the Power factor. It is the ratio of applied power over the required power.

construction and principle of operation asynchronous machine

A linear induction motor LIM is an alternating current AC , asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects, whereas a conventional induction motor is arranged in an endless loop. Despite their name, not all linear induction motors produce linear motion; some linear induction motors are employed for generating rotations of large diameters where the use of a continuous primary would be very expensive. As with rotary motors, linear motors frequently run on a three-phase power supply and can support very high speeds. However, there are end-effects that reduce the motor's force, and it is often not possible to fit a gearbox to trade off force and speed. Linear induction motors are thus frequently less energy efficient than normal rotary motors for any given required force output.

Linear induction motor

In the early years of the 20th century, when rotating electrical machines had become established and made to perform satisfactorily, it was realised that these machines could be made in a different form which would use or produce motion in a straight line, instead of the normal rotary motion.

Principle of Operation A rotating field is set up in the stator when a 3- Phase supply is given. The stationary rotor cut the revolving. Working Principle of AC Motors. Induction motor works on the principle that whenever a closed conductor is placed in a magnetic field. Electric motor - Electric motor - Construction of induction motors: The stator When operated from a constant-frequency supply the three-phase induction motor. The rotor of a three phase induction motor can never attain synchronous speed. It is connected with two windings namely.

Facebook Twitter. So it is called Reluctance Motor. Here we will discuss construction and working principle of Reluctance Motor. The reluctance motor has basically two main parts called stator and rotor. The stampings are slotted on its periphery to carry the winding called stator winding. The stator carries only one winding.


Linear Induction Motor (LIM) is an asynchronous motor, working on the same principle an Induction Motor works, but is designed to produce the.


Tesla Polyphase Induction Motors

Он жертвует всеми планами, связанными с Цифровой крепостью. Хейл не мог поверить, что Стратмор согласился упустить такую возможность: ведь черный ход был величайшим шансом в его жизни. Хейлом овладела паника: повсюду, куда бы он ни посмотрел, ему мерещился ствол беретты Стратмора.

В АНБ сосредоточена самая секретная государственная информация: протоколы военной связи, разведданные, списки разведчиков в зарубежных странах, чертежи передовой военной техники, документация в цифровом формате, торговые соглашения, - и этот список нескончаем. - Танкадо не посмеет этого сделать! - воскликнула.  - Уничтожить всю нашу секретную информацию? - Сьюзан не могла поверить, что Танкадо совершит нападение на главный банк данных АНБ. Она перечитала его послание.

Ей казалось, что она слышит его голос, зовущий ее, заставляющий спасаться бегством, но куда ей бежать. Шифровалка превратилась в наглухо закрытую гробницу. Но это теперь не имело никакого значения, мысль о смерти ее не пугала. Смерть остановит боль. Она будет опять рядом с Дэвидом.

Chapter 13 - AC Motors

Лицо его было несчастным. - Я думал, вы из городского… хотите заставить меня… - Он замолчал и как-то странно посмотрел на Беккера.  - Если не по поводу колонки, то зачем вы пришли. Хороший вопрос, подумал Беккер, рисуя в воображении горы Смоки-Маунтинс. - Просто неформальная дипломатическая любезность, - солгал. - Дипломатическая любезность? - изумился старик. - Да, сэр.

Сьюзан пыталась отстраниться, но он не отпускал. ТРАНСТЕКСТ задрожал, как ракета перед стартом. Шифровалка содрогалась. Стратмор сжимал ее все сильнее.

Должно быть что-то самое простое. Техник в оперативном штабе начал отсчет: - Пять. Четыре.

    The basic design and construction of a linear induction motor is similar to a three phase induction motor, although it does not look like a conventional induction motor. If we cut the stator of a polyphase induction motor and lay on a flat surface, it forms the primary of the linear induction motor system.
