Electric Machine Design Methodology: A Revolutionary Approach - White Paper
Electric machines are used in novel applications around the world, driven by the need for greater power efficiency in the transportation, aerospace and defense, and industrial automation industries. The automotive sector focuses on the need for hybrid and electric vehicle technology to meet stringent miles-per-gallon standards. The aerospace and defense industry concentrates on replacing existing aircraft power transfer technologies (such as the central hydraulic system) with fault-tolerant electric power, in which major subsystems — including engine starting, primary flight control actuation, pumps and braking — are controlled and driven electronically. In the United States’ industrial sector, more than 40 million electric motors convert electricity into useful work in manufacturing operations. Industry spends over $30 billion (US) annually on electricity dedicated to electric motor-driven systems that drive pumps, fan and blower systems, and air compression.
