Short Desciption:
Electric motors are a fundamental component in almost all industries. It is known that electric motors consume about 60% of the electrical energy produced in industrialize nations [1]. Recently, electric motors have attracted more attention as automakers prepare for the mass production of electric vehicles. Despite a long history of research on electric motors, there still remains room to enhance the motor performance. As noted by Mitsuhiko Yamashita, Executive Vice President of Nissan Motor Co., Ltd [2] , “Motor technology is very old. There has been no big progress recently because people didn’t pay much attention to motor technology”.

Summary:
This research presents an approach to find the optimal geometry for improving performance of electric motors. The performance of electric motors can be improved by two ways: a) by changing their geometry, and/or b) by modifying their control scheme. Contrary to a vigorous research effort on control optimization, more research to find the optimal geometry remains. In this research, we aim to fully investigate a structural topology optimization approach to magnetic fields, which can identify ways to change 2 the geometry of high performance electric motors. Among various motor performances, we mainly focus on the force/torque density which can be enhanced by maximizing the force/torque with the minimum amount of mass. The magnetic force/toque is calculated numerically using the finite element method with various calculation methods. To investigate the characteristics of magnetic force/torque with respect to its geometry or material property, the magnetic actuator is optimized as a basic study. By examining optimization results, the properties of magnetic circuit parameters such as nonlinear permeability, geometry, and mass are investigated. From this basic study, we seek a guideline to design the magnetic circuit of electric motors that improve the force/torque performance.
