Abstract
Fully integrated electric propulsion systems are gaining popularity in both commercial and military sectors. Propulsion motor manufacturers are investigating new direct-drive solutions for use in electric ships. These applications require motors with high torque output at low speeds. Such requirements were the motivation for the design of a new permanent-magnet synchronous motor (PMSM) with a novel topology. This paper describes the efficient mathematical model used to optimize our PMSM design. Based on a simplified theoretical model for the motor's behavior, we were able to quickly and accurately predict torque output. The minimalist design of this transverse flux machine is shown to be advantageous for computer simulation and machine manufacturing. Initial results from a prototype are included and discussed. Future plans for the prototype are outlined.
