title = "Scaling Study of High Frequency Machine for Electric Aircraft Propulsion",
abstract = "High-frequency, 'air-core' machine topologies is found to have advantages in specific power for high-speed applications. The benefit in lower weight of the motor is especially attractive when considered for aerospace application, such as electric propulsion for aircraft. In this paper, we explore how these machines scale to electric propulsion systems at a range of speeds. Analytical model used to calculate magnetic and electric loading is detailed. Iron loss and copper loss model characterization is presented. An evolutionary genetic algorithm is utilized to study the effect of speed on weight of the topology. The results show that the air-core topology mantains high specific power even at lower speeds.",
