In electrical machines, the modularity by making the stator in multiple parts brings many advantages. The ability to create machines of different power using the same E-cores,to be scalable, is very important in terms of production and transportation costs. In this study, E-core design for a modular and scalable PMSG is discussed. E-core dimensions are determined by considering magnetic and electrical loading, magnetic coupling, torque ripple, cogging torque, voltage harmonics, etc. apart from enabling the creation of different slot/pole combinations. Core and magnet sizes are determined analytically and FEM analysis of two selected models have been performed. Prototypes of machines with slot/pole combinations of 24/22 and 48/46 and rated power of 2.5kW and 5kW respectively have been manufactured with the same E-cores.
