New Trends in Electrical Machines Technology-Part I

The electrical machines technology is in permanent evolution even though their basic principles were invented more than 200 years ago. For any amount of power rate, all moving electromechanical devices need design, manufacturing, testing, condition monitoring, and control techniques. This way, industrial electronics is without any doubt a key partner of electrical machines in their real environments with applications of sensors, power converters, digital control circuits, and more. The cross-coupling effects on the direct-axis and the quadrature-axis synchronous inductances have been considered, such as the loss distribution and the efficiency. By means of the experimental validation of a prototype, authors have proved that the designed motor is able to produce its rated torque with the rated current in a very wide speed range. It is interesting to observe that some experimental data have been recorded during a road-legal electric vehicle race.
