Electric Motors Handbook Volume 1
The Electric Motors Handbook examines how these important devices play a critical role in all aspects of our modern society. More than 50 per cent of all electricity generated is consumed by this equipment.
In fact, 75 per cent of all industrial electricity consumption is consumed by this equipment. In order to select and apply the correct size electric motor, electrical personnel must be aware of all factors involved: energy efficiency, sizing and proper application. equipment management (protection, control and maintenance) is also critical to achieving efficient use and maximum life expectancy.
This 96 page book will present articles from leading experts on selection, how they work, application, protection and control, maintenance and troubleshooting in modern electrical systems.

Product Description: Most devices work by electromagnetism, but other types, based on other electromechanical phenomena, such as electrostatic forces and the piezoelectric effect, also exist. The fundamental principle upon which electromagnetic devices are based is that there is a mechanical force on any current-carrying wire contained within a magnetic field. The force is described by the Lorentz force law and is perpendicular to both the wire and the magnetic field. Most magnetic types are rotary, but linear types also exist. In a rotary device, the rotating part (usually on the inside) is called the rotor, and the stationary part is called the stator. The rotor rotates because the wires and magnetic field are arranged so that a torque is developed about the rotor's axis. The device contains electromagnets that are wound on a frame. Though this frame is often called the armature, that term is often erroneously applied. Correctly, the armature is that part of the device across which the input voltage is supplied. Depending upon the design of the machine, either the rotor or the stator can serve as the armature. - Wikipedia
