The present work proposes the design and development of a didactic Scott transformer where all mains windings are available. This presents the mathematical equations that describe the behavior of the module and its fasorial analysis for 3Φ-2Φ, 2Φ-3Φ and 3Φ-4Φ conversion. Winding indutances and output voltages obtained by experimental tests are compared to digital simulations with the OrCAD/PSpice tool, Schematics. Practical experiments are planned to prove 3Φ-2Φ conversion, efficiency curve, regulation and the possibility of starting a single-phase induction motor without capacitors.
