An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current DC sources, such as from batteries, or rectifiers , or by alternating current AC sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output.

In electrical engineering , electric machine is a general term for machines using electromagnetic forces , such as electric motors , electric generators , and others. They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to electricity. The moving parts in a machine can be rotating rotating machines or linear linear machines. Besides motors and generators, a third category often included is transformers , which although they do not have any moving parts are also energy converters, changing the voltage level of an alternating current.

Техники сновали по комнате. Что-то подсказывало Сьюзан, что они близки к разгадке. - Мы можем это сделать! - сказала она, стараясь взять ситуацию под контроль.  - Из всех различий между ураном и плутонием наверняка есть такое, что выражается простым числом. Это наша главная цель.

Если твоя проверка выявила нечто необычное, то лишь потому, что это сделали мы. А теперь, если не возражаешь… - Стратмор не договорил, но Чатрукьян понял его без слов.
