Fundamentals of Electric Machines

Part of the Advances in Industrial Control book series (AIC)


The efficiency of the electric rotating machines is an increasingly important point to take into account in the design of applications with rotary loads. The advanced design of the AC machines with finite element analysis (FEA), increasingly allow obtaining high-performance designs and high power density machines. Join with sophisticated control systems and the appropriate hardware, the operation in a wide range of speed is optimized. The result is that lower-performance machines such as brushed machines are being displaced in many applications. This chapter shows a classification of the most common electrical machines starting with the more traditional machines such as the DC-brushed and induction machines and finishing with more sophisticated machines such as the synchronous reluctance machine. Their primary structures, their mathematical expressions in a steady-state, in space vector, in dqs transformations, and the electromagnetic torque expression for each machine are shown. All this analysis permits to extract the most suitable model for its simulation and to optimize the control as it will be seen in Chap.  5. Moreover, basic concepts of machine design, sections of different machines, and simulation results are introduced based on Altair, FluxTM, and FluxMotorTM software packages.
