LabVIEW for Electric Circuits, Machines, Drives, and Laboratories by Nesimi Ertugrul,
LabVIEW for Electric Circuits, Machines, Drives, and Laboratories by Nesimi Ertugrul,
The first interactive, LabVIEW-based guide to electrical system analysis and operation. For the first time, you can master electric circuits, machines, devices, and power electronics, hands on-without the use of expensive equipment. Using custom-written LabVIEW Virtual Instruments, Nesimi Ertugrul walks you through every key topic associated with the analysis and operation of a wide range of AC and DC circuits, electrical machines, and drives-including high-voltage/current/power applications covered in no other book. Ertugrul presents detailed background on every topic, along with full VI panels, complete laboratory practices, hardware information, wiring diagrams, printed circuit layouts, and self-study questions: everything you need to achieve true mastery.Periodic waveforms, harmonics, equivalent circuits, and DC circuit analysisAC circuit analysis, phasors, complex powers, power factor correction, and three-phase AC systemsMagnetic circuits, BH characteristics, and lossesTransformers, asynchronous motors, synchronous machines, stepper motors, brushless permanent magnet motors, and switched reluctance motorsDiode and SCR conduction, diode rectifiers, AC choppers, cycloconverters, and invertersAdvanced motor drives and control techniquesCD-ROM INCLUDED The accompanying CD-ROM contains a complete copy of LabVIEW 6 Evaluation Version, plus all Virtual Instrumentations (VIs) presented in the book, enabling readers to test diverse operating conditions for a wide range of circuits.



Permanent magnet motor - The permanent magnet motor was concieved by Howard Robert Johnson sometime after the 1940s. Alledgedly it is a design for a perpetual motion machines.

Rare-earth magnet - A rare-earth magnet is a special permanent magnet made out of the elements located in the lanthanides and actinides series of the periodic table. These rare-earth elements are combined with more common elements to form compounds that possess very powerful ferromagnetic properties.

Magnet therapy - Magnet therapy, or magnetic therapy, is a form of alternative medicine based on the claim that certain medical disorders can be effectively treated by exposure to magnetic fields. Some believe that magnetic fields emanating from permanent magnets placed close to the body can cause bones to heal faster, relieve pain, and perform other forms of healing to the body.

Molecular magnet - Molecular magnets are systems where a permanent magnetization and magnetic hysteresis can be achieved (although usually at extremely low temperatures) not through a three-dimensional magnetic ordering, but as a purely one-molecule phenomenon.

Design of Brushless Permanent-Magnet Motors The first interactive, LabVIEW-based guide to electrical system analysis and operation. Some designs may appear to work on paper at first glance, but have various flaws or obfuscated external power sources that render them useless in practice; others remain untested. Overview For millennia it was not clear whether such devices were possible, but the development of modern thermodynamics has led virtually all engineers and scientists to agree that they are impossible. The USPTO granted a few patents for motors that are claimed to run without net energy input. Patents This sort of "invention" has become common enough that the United States Patent and Trademark Office (USPTO) has made an official policy of refusing to grant patents for perpetual motion machines dates as far back as the 13th century, and probably further. Zimara designed a self-blowing windmill that generated power from a set of permanent magnet motor.
