Abstract
Optimization-based design of electric machinery over a large design space requires the use of computationally efficient models to predict machine behavior. In this research, an analytical design model is developed for wound rotor synchronous machines, a key technology for power generation. The model is designed to be used in a rigorous multi-objective optimization algorithm, providing the trade-off between competing mass and loss objectives. A formalized approach is presented to calculate the field distribution, as well as qd -axis model parameters, terminal quantities, loss, and developed torque from design data containing material properties, stator and rotor geometries, and winding layout. The calculated parameters include resistances, inductances, and the back-EMF of the machine. The model is verified using finite element analysis and hardware experiment.
