Electrical Motor

Get greater flexibility, reliability, and reduced energy consumption from household appliances to automobiles. This book will show you how different types of motors operate and how electronic control devices can be used to improve efficiency in a wide range of applications. You'll get in-depth, updated coverage of: Electric motor control applications; dc and ac motors; Digital motors; Commutator-type motors; Noncommutator-types motors; Electric vehicles.

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.

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.

Brushless DC electric motor - A brushless DC motor (BLDC) is a DC electric motor that uses an electronically-controlled commutation system, instead of a mechanical commutation system. (The rest of this article assumes the reader is familiar with the principles of electrical motors.

Electrical component - An electrical component is any component in the generation, transmission, distribution, or consumption of electric power. Some examples of these components would be: relays, contactors, timers, circuit breakers, fuses, and motor starters.

Motor-generator - A motor-generator (an M-G set) is a device for converting electrical power to another form. In some contexts, the other form is mechanical energy; in other contexts, it is a different form of electricity.
