Integrated design methodology for electrical drives: a marine application experience

This paper presents an original experience in the design of electrical drives. A complete integration has been realised among the design of the motor, power converter and control. This solution became possible thanks to the application of a software tool called Electromechanical System Simulator (EMSS), whose Finite Element Method (FEM) core is Maxwell2D, that allowed the electromagnetic design of the motor and then the generation of a SPICE model of this device so to allow the analysis of the interaction with the power converter and the control structure. This solution presents the interesting aspect of reaching an high detail in the analysis of the electromagnetic field inside the machine without disregarding the circuit-based approach of the converter design
