Low voltage Induction motors

The manuscript of this book was first prepared at the request of the Institution of Electrical Engineers in 1971. This coincided with a period of great activity in one particular aspect of linear motors, that of high-speed ground transport (HSGT) applications. It was a time when the Tracked Hovercraft project showed such great promise, when new inventions grew like mushrooms and hopes for a world-adopted British system ran high, only to be dashed by the Government's closure of the project in 1973 and demolition of the full-scale track in 1974. It was a time when personal emotions ran high.

The following pages are meant for those who wish to use thyristors. The details of the physics of semiconductor materials or the design of thyristors themselves are unnecessary here but a general description of the device may help to avoid pitfalls during electric circuit design.

Controlling the level of noise in electrical motors is critical to overall system performance.

learn all the Fundamentals of DC Electric Circuits in an Easy and simple way with Many examples and Applications.

In this revised and expanded edition, Howard E. Jordan explains-in a clear manner-the technology of energy efficient electric motors including motor losses, testing, and efficiency labeling. He also discusses how to calculate the return on investment for an energy efficient motor in addition to several other subjects related to effective motor applications. New chapters explore permanent magnet synchronous motors and transistor pulse-width-modulated inverters. Engineers, purchasing managers, and executives who make decisions on motor selection will find this an invaluable reference.
