The objective of this proposed effort is to increase the power and torque density of rotating electric machinery for Naval applications by up to 50%. This aggressive goal will be achieved by developing the novel homopolar AC machine (HAM) topology. This relatively un-studied topology relies on solenoidal field and armature coils, making manufacturing simpler than traditional machines. The HAM eliminates rotating field windings and rotor bars, thereby improving thermal performance without the use of fragile and expensive permanent magnets. Using multi-objective optimization methods, we will develop design tools to predict and optimize the performance of this novel machine topology and validate those tools via finite element analysis. Plans and detailed design documentation for construction of a scaled prototype machine will be developed.
