Conversion of Three-phase Commercial Machines into Six-phase Machines for Didactic and Research Purposes

Generally poly-phase machines are called those with more than three phases (> 3ph), these have acquired importance in recent years in specific applications such as wind power, electric vehicles, aeronautics, boat propulsion, etc. Its main advantage lies in fractionate power in large machines (ships, wind) and fault tolerance to low power machines (aeronautics, electric vehicles). Because they are special machines, it is interesting to study the calculation and design of this type of machines. Therefore, the conversion of two three-phase permanent magnets machines in two poly-phase machines of six phases with different combinations of windings in the stator and different types of rotors is presented. These machines are designed for teaching tasks in the course of electrical machines and as prototypes of test in research tasks. In the present work, the process of calculation and design of two poly-phase machines that are simulated with simulations with the method of finite elements and experimentally validated are detailed.
