Electric motors play an essential role in almost every industry. Using the right type of motor with high-quality parts and regular servicing keeps your facility running smoothly and prevents damage to the endpoint equipment due to wear or power surges. Gainesville Industrial Electric can help your company select the right industrial electric motors and parts for your applications.

While both A. C wound field motors are constructed with brushes and a commutator, which add to the maintenance, limit the speed and usually reduce the life expectancy of brushed D.

Even though annealed at the mill, fully processed material may require further stress relief anneal after stamping. The stresses introduced during punching degrade the material properties around the edges of the lamination, and must be removed to obtain maximum performance. Because of its lower electrical conductivity, aluminum wire requires a 1. Insulation Modern magnet wire typically uses one to four layers of polymer film insulation, often of two different compositions, to provide a tough, continuous insulating layer. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describes nominal geometry and its allowable variation.

Topical worksheets

The AC Motor and the DC Motor are differentiated on the various factors like the source or the nature of the power used in the motor. The commutation process, types, starting of the motor, a number of terminals. Applications of the motor, usage of brushes and the maintenance cost of the motor. In an AC Motor , an alternating current passes through the coils. When an alternating current is passed on the electromagnets is a magnetic field is generated. Stationary parts consist of the electromagnets.

Together, these worksheets constitute a body of questions far too large to be comprehensively covered in any single electronics course. That is not the point, though. This collection is purposely oversized so you may pick and choose enough questions to meet your specific teaching needs. Download those worksheets containing questions you wish to use, and then only assign those questions to your students for research and discussion. The rest may be ignored, or your students may find them useful as study aids outside of class. Although I strive to make each of these worksheets self-contained, some topics will necessarily assume coverage of prior topics.


This chapter deals with the basic mechanisms of motor operation, so readers who are which are used with motor drives, providing either d.c. or a.c. outputs.


Difference Between AC and DC Motor

Theoretically, the same DC machine can be used as a motor or generator. Therefore, construction of a DC motor is same as that of a DC generator. An electric motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of a DC motor is: " whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force". Fleming's left hand rule : If we stretch the first finger, second finger and thumb of our left hand to be perpendicular to each other, and the direction of magnetic field is represented by the first finger, direction of the current is represented by the second finger, then the thumb represents direction of the force experienced by the current carrying conductor.

Цель была достигнута. Все глобальное электронное сообщество было обведено вокруг пальца… или так только. ГЛАВА 5 Куда все подевались? - думала Сьюзан, идя по пустому помещению шифровалки.  - Ничего себе чрезвычайная ситуация.

What is the difference between an AC motor and a DC motor?

Сьюзан задумалась о том, почему он задерживается так долго, но ей пришлось забыть о тревоге за него и двигаться вслед за шефом. Стратмор бесшумно спускался по ступенькам. Незачем настораживать Хейла, давать ему знать, что они идут.

Он вообще не в курсе дела. Сьюзан смотрела на Стратмора, не веря своим ушам. У нее возникло ощущение, что она разговаривает с абсолютно незнакомым человеком. Коммандер послал ее жениха, преподавателя, с заданием от АНБ и даже не потрудился сообщить директору о самом серьезном кризисе в истории агентства. - Вы не поставили в известность Лиланда Фонтейна.

Сигналы продолжались. Источник их находился где-то совсем близко. Сьюзан поворачивалась то влево, то вправо. Она услышала шелест одежды, и вдруг сигналы прекратились. Сьюзан замерла.

Если Грег Хейл ворвется… - Он не закончил фразу. Сьюзан потеряла дар речи. Он пристально посмотрел на нее и постучал ладонью по сиденью соседнего стула. - Садись, Сьюзан. Я должен тебе кое-что сказать.  - Она не пошевелилась.

Джабба повернулся и изумленно посмотрел на. - Танкадо. Сьюзан едва заметно кивнула: - Он требовал, чтобы мы сделали признание… о ТРАНСТЕКСТЕ… это стоило ему… - Признание? - растерянно прервал ее Бринкерхофф.  - Танкадо требует, чтобы мы признали существование ТРАНСТЕКСТА. Но он несколько опоздал. Сьюзан хотела что-то сказать, но ее опередил Джабба: - Значит, Танкадо придумал шифр-убийцу.  - Он перевел взгляд на экран.
