Summary: This paper examines the impact of cogging torque and unbalanced radial magnetic forces on vibrations and acoustic noise properties in concentric magnetic gears through three physical demonstrators with unique properties. It shows how these factors dominate the acoustic and vibrational properties and affect the sensitivity of the magnetic gears to system eigenfrequencies.

Summary: This paper introduces a new high power density permanent magnet motor design for traction applications, aiming to achieve a 50kW/L target. A multi-objective design optimization was conducted based on finite element analysis and differential evolution algorithm to balance efficiency, power density, and power factor, while maintaining a constant power speed ratio. An open frame lab prototype motor was fabricated and tested to validate the design principles and identify challenges in manufacturing and testing. Ongoing work includes further improving electromagnetic performance and manufacturing and cooling techniques.

Summary: This paper demonstrates that high torque density can be achieved in a coaxial magnetic gear system with a high gear ratio by selecting the right radius and conducting careful radial parameter sweep analysis. An example design with a 33:1 gear ratio and torque density exceeding 300 Nm/L is presented, along with a direct comparison of torque density between the Halbach rotor MG and the surface mounted permanent magnet MG.
