Theoretically, the same DC machine can be used as a motor or generator.

A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.

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. Electric motors are machines that convert electrical energy—from either stored power or a direct electrical connection—into mechanical energy through the production of rotational force. The two major types of electric motors are:. Both AC and DC motors use electrical current to produce rotating magnetic fields that, in turn, generate rotational mechanical force in the armature—located on the rotor or stator—around the shaft.

How a DC motor works?

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.


Both AC and DC motors must be manufactured with a great deal of precision in order to operate properly. LEESON and other major manu- facturers use laminated.

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.

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. The final basic difference is speed control. The speed of a D. Information needed for fast response.

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

 - Давай ключ. Я жду. Бринкерхофф застонал, сожалея, что попросил ее проверить отчет шифровалки.

Difference Between AC and DC Motor

Телефонистка отвесила еще один поклон: - Я говорила с телефонной компанией. Звонок был сделан из страны с кодом один - из Соединенных Штатов. Нуматака удовлетворенно мотнул головой. Хорошая новость.

 - Отключение вручную займет минут тридцать. Фонтейн по-прежнему смотрел на ВР, перебирая в уме остающиеся возможности. - Директор! - взорвался Джабба.  - Когда эти стены рухнут, вся планета получит высший уровень допуска к нашим секретам. Высший уровень. К отчетам о секретных операциях.

A Primer on Electric Motors

Ноги несли его с такой быстротой, на какую, казалось ему, он не был способен. Когда он влетел во вращающуюся дверь, прозвучал еще один выстрел. Стеклянная панель обдала его дождем осколков. Дверь повернулась и мгновение спустя выкинула его на асфальт. Беккер увидел ждущее такси. - Dejame entrar! - закричал Беккер, пробуя открыть запертую дверцу машины.

В парке. Это было убийство - Ermordung.  - Беккеру нравилось это немецкое слово, означающее убийство.
