An AC motor is an electric motor driven by an alternating current AC. The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field , and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings. Less common, AC linear motors operate on similar principles as rotating motors but have their stationary and moving parts arranged in a straight line configuration, producing linear motion instead of rotation. The two main types of AC motors are induction motors and synchronous motors. The induction motor or asynchronous motor always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding.

PDF This paper explores the construction process of a linear induction motor LIM , the basic concepts behind key aspects of linear induction machines construction and the testing process of a working prototype. The single-phase induction motor is much the same in construction as the three-phase motor. There are two types of 3-phase induction motor based on the type of rotor used: Squirrel cage induction motor. Slip ring induction motor. Construction of Induction Motor Construction of an Induction Motor, 3 phase induction motor construction, induction motor construction, working ppt, induction Three phase induction motor construction.

What is AC Motor – Definition, Operation and Applications

The conversion of energy from electrical to mechanical was explained by Michael Faraday, a British scientist in the year The energy conversion can be done by arranging a current carrying conductor within a magnetic field. So the conductor starts rotating because of the generated torque from the magnetic field and electrical current. So finally, the first electric motor was invented in the year by Frank Julian Sprague. An electric motor can be defined as; it is one kind of machine used to convert the energy from electrical and mechanical. These motors can be triggered by a DC source or AC source.

Some of the advantages like low cost, rugged design less complex, and easy to maintain AC motors results in many of the industrial operations are performed with the use of AC drives than DC drives. AC induction motor is a special type of electric motor having its own typical characteristics and performance in terms of starting, speed control, protections, and so on. The performance over a wide range of applications makes three-phase induction motors accountable for 85 percent of the installed capacity of the industrial driving systems. The three-phase AC induction motor is a rotating electric machine that is designed to operate on a three-phase supply. This 3 phase motor is also called as an asynchronous motor. These AC motors are of two types: squirrel and slip-ring type induction motors. The principle of operation of this motor is based on the production of a rotating magnetic field.


This explains Three Phase Induction Motor Construction & Working Principle.​Advantages and disadvantages of 3 phase induction motors.


Electric Motor Working and Its Applications

A device that transforms the form of input electrical energy to an output mechanical energy. Basically, there are two types of electrical motors they are the DC and AC type. The DC type machines are normally used in small applications whereas the AC type has its importance in a wide range of applications. Because the AC machines have more advantages compared to that of DC machines.

Стратмор развернул монитор так, чтобы Сьюзан было. Экран отливал странным темно-бордовым цветом, и в самом его низу диалоговое окно отображало многочисленные попытки выключить ТРАНСТЕКСТ. После каждой из них следовал один и тот же ответ: ИЗВИНИТЕ.

Он подошел ближе.  - Я опытный диагност. К тому же умираю от любопытства узнать, какая диагностика могла заставить Сьюзан Флетчер выйти на работу в субботний день.

What is an Electric Motor?

Соши смотрела на монитор и читала вслух: - В бомбе, сброшенной на Нагасаки, использовался не плутоний, а искусственно произведенный, обогащенный нейтронами изотоп урана с атомным весом 238. - Черт возьми! - выругался Бринкерхофф.  - В обеих бомбах уран. Элементы, ответственные за Хиросиму и Нагасаки, - оба являются ураном. Никакого различия. - Мы погибли, - прошептала Мидж.

Сердце Беккера подпрыгнуло. - Очень хорошенькие? - повторил он с нарочитым немецким акцентом.  - Рыженькие. - Да, а как зовут вашего брата. Я скажу вам, кто его сегодня сопровождает, и мы сможем прислать ее к вам завтра. - Клаус Шмидт, - выпалил Беккер имя из старого учебника немецкого. Долгая пауза.

Вой сирен вывел его из задумчивости. Его аналитический ум искал выход из создавшегося положения. Сознание нехотя подтверждало то, о чем говорили чувства. Оставался только один выход, одно решение. Он бросил взгляд на клавиатуру и начал печатать, даже не повернув к себе монитор.

 Его погубило слабое сердце - вот так. Слишком уж удобная версия. Стратмор пожал плечами. - Слабое сердце… да к тому же еще испанская жара.

 - Я же терпеть не могу мотоциклы. Он крикнул парню: - Десять тысяч, если отвезете меня в аэропорт. Тот даже не повернул головы и выключил двигатель. - Двадцать тысяч! - крикнул Беккер.

Конец веревочки. Он набрал номер. - Escortes Belen, - ответил мужчина.

Он все протягивал к нам руку - чтобы мы взяли кольцо. Я не хотела брать, но мой спутник в конце концов его. А потом этот парень умер.

 Так полицейский сказал вам, что это я взял кольцо. Беккер смущенно подвинулся. Клушар вдруг разбушевался. - Я знал, что он меня не слушает.

Все закончилось.
