520			_a"Electrical machines are usually rotating devices creating electromagnetic torque due to the magnetic coupling field. The machines perform electromechanical conversion of energy; thus, they are called rotational converters. The stationary part of rotating machines is called stator. The mobile part which rotates is called rotor. There are two basic electromagnetic phenomena at play in rotating electrical machines. When a conductor moves relative to magnetic field, a potential difference is induced in the conductor. Electric motors operate on one of three physical principles: magnetism, electrostatics and piezoelectricity. In magnetic motors magnetic fields are formed in both the rotor and the stator. The product between these two fields gives rise to a force, and thus a torque on the motor shaft. One, or both, of these fields must change with the rotation of the rotor. This is done by switching the poles on and off at the right time, or varying the strength of the pole. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be brushed or brushless, single-phase, two-phase, or three-phase, axial or radial flux, and may be air-cooled or liquid-cooled. In this book a general matrix-based approach to modeling electrical machines is promulgated. This comprehensive book helps energy professionals to understand the state-of-the-art in rotating electrical machines and power systems"-- Back cover.
