AC Electrical Generators

Rotating armature AC generators are typically used in applications involving small amounts of power With larger amounts of power, a great deal more current flow occurs through the slip rings and brush It is difficult and expensive to build slip rings and brushes to carry large amounts of current Therefore, most large AC generators are...

Electric Drives

Electrical Machines - Electric Drives (Fundamentals) Principles Motor Action; Michael Faraday showed that passing a current through a conductor freely suspended in a fixed magnetic field creates a force which causes the conductor to move through the field...

Alternating current

The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa In certain applications, like guitar amplifiers, different waveforms are used, such as triangular or square wav...
