Electrical Motor Control

Drawing from the author's 20+ years professional and academic experience, this book presents basic AC and DC electricity, electrical principles, electric circuits and controls for air conditioning, heating and refrigeration systems. It is specifically designed to be clear and concise enough for beginners--with a straightforward writing style and numerous diagrams and illustrations--yet comprehensive and accessible enough to serve as a professional reference. Chapter topics include safety; tols for HVAC technicians; fundamentals of electricity and electrical meters; series circuits; parallel and series-parallel circuits; magnetic theory; fundamentals of AC electricity; transformers, three-phase, and single-phase voltage; symbols and diagrams for HVAC and refrigeration systems; relays, contactors, and solenoids; single-phase open motors; single-phase hermetic compressors; three-phase open motors and three-phase hermetic compressors; motor starters and overcurrent controls; thermostats and heating controls; pressure controls, timer controls, and other controls; electronic devices for HVAC systems; electrical control of heating and air-conditioning systems; electrical control of heat pump and refrigeration systems; and direct digital control systems. For service technicians, HVAC technicians, contractors, and HVAC installers.

This book is a comprehensive reference source for practicing engineers and students specializing in electric power engineering and industrial electronics. It will illustrate the state of the art in induction motors. Beginning with characteristics and basic dynamic models of induction motors, and progressing to low- and high- performance drive systems. The book will be rich in useful information, without an excessive mathematical burden. Computer simulations resulting in mock oscillograms of physical quantities are used for illustration of basic control concepts. The content of this book is divided into three basic parts: 1) control-oriented description of induction motors, 2) control methods, and systems, 3) control means. An induction motor is presented as an electromechanical power converter, and basic relations between the electrical, magnetic and mechanical quantities in the motor will be explained. Control methods and systems will be classified according to the controlled variables(torque, speed, flux), actuating variables(voltage, current), and dynamic performance (uncontrolled, low-performance, and high-performance). An overview of power electronic converters and information processing equipment used in the modern induction motor drives is included. Such systematic approach will give the readers a comprehensive overview of the field of induction motor control.

Digital Command Control - Digital Command Control (DCC) is a scheme for controlling locomotives on a model railroad layout that allows more than one locomotive to occupy the same electrical section of track. Each of the locomotives has a decoder between the track and the motor, an electronic circuit that reads messages sent over the track and controls the amount of electricity delivered to the motor.

Motor Vehicle Air Pollution Control Act - The Motor Vehicle Air Pollution Control Act is a 1965 amendment to the Clean Air Act of 1963. It set the first federal vehicle emissions standards beginning with the 1968 models (which were the same standards California had set for their 1966 models.

Industrial plant - ... of processing equipment, storage systems and conveyances configured to convert or move raw material into a more useable form or location. Industrial plant generally incorporates various mechanical processing devices; piping and conveyors; buildings and structures; utilities including water and power supply; electrical power distribution; motor control centres; and control, communications and information systems.

Electric motor - An electric motor converts electrical energy into mechanical motion. The reverse task, that of converting mechanical motion into electrical energy, is accomplished by a generator or dynamo.
