Extended semi-analytical model of bipolar hybrid stepper motor

The aim of this graduation thesis is to present a bipolar stepper motor semi-analytical model and compare its simulated motor dynamics. Stepper motor modeling has been successfully used to simulate motor performance and dynamics, yet, each modeling method holds advantages and disadvantages toward one another. In this thesis, the analytical...

Development of a multiobjective design optimization procedure for marine propellers

The design of a marine propeller is characterized by its complexity rather then its shortcoming of knowledge how to asses its performance. There are several constraints to satisfy and all are in a different field. The three major considerations are strength, performance (efficiency) and cavitation behavior. There is not a perfect design...
