【内容简介】
With major recent developments in informatics technologies globally, many universities have downsized their electric power curriculum. In an era of power electronics and DSP embedded control, this book separates power electronics and control of electric machines, concisely and expertly exploring the many facets of rigor associated with electric machines. Taking advantage of the considerable theory and design heritage of electric machines, and computer tools now available to simulate complex systems in real time, this comprehensive, unified treatment covers steady state and transient operation, Finite Element (FE) analysis and optimal design transformers, as well as permanent magnet DC brushes and variable reluctance motors.
