Energy-efficient steels for motor laminations
Journal of Materials Engineering and Performance, 1992Motors use over 60% of all electricity generated, and their losses exceed 200 × 109 kW.hr/year. A significant part of this loss results from eddy currents and hysteretic processes in the motor laminations. These so- called core losses cost motor users about $3 × 109/year.

Technology of Energy-Efficient Motors
1994Electric motors function as energy converters changing electrical to mechanical energy and are one of the most efficient means of energy conversion known. Although some losses do occur in the conversion process, the majority of the electrical energy which enters the motor is converted to mechanical form and delivered to the load. Consider Fig.

Energy-efficient control of induction motors for automotive applications
The XIX International Conference on Electrical Machines - ICEM 2010, 2010The main features of an electric drive for electric vehicles (EVs) should be the capability to exploit the maximum torque in the whole speed range, a weak dependence on the motor parameters, a good robustness against the variations of the dc-link voltage and, whenever possible, the maximum efficiency. In this paper a control scheme for induction motors,
