Special Session SS02

Improving Power Density of Electrical Machines by Application of Advanced Materials


Introduction:

High-power-density motors have several remarkable advantages such as compact size, high efficiency, excellent dynamic performance, etc. Improving the power density of electric machines has already become a hot topic in research and will continue to be so for a long time. According to the principle of electrical machines, the power density is proportional to the surface current density, fundamental air-gap flux density, and rotational speed, which are limited by the current-carrying ability of conductors, losses and capability of cooling system, remanent magnetic field of permanent magnets, saturation flux density of stator and rotor core, as well as mechanical stress of rotor materials, etc. To address the aforementioned limitations, advanced high-performance materials play a key role. For instance, superconductors with higher current-carrying capacity, metallic oxide insulating materials with higher working temperature, heat pipes with higher cooling capacity, can help to increase the surface current density; Ferromagnetic materials with higher saturation magnetic induction intensity and permanent magnet materials with higher remanence can help to increase the fundamental air-gap flux density; Dual-phase ferromagnetic materials and high-strength composite materials can help to increase the rotation speed. However, there are still many problems regarding how to better apply these advanced materials in electric motors. Therefore, with an aim to improve the power density, this session will mainly discuss and tackle the issues due to the application of advanced materials to electric machines. Topics of interest include, but not limited to the following aspects:
1. Innovate motor structures
2. Multi-physics simulations
3. Design optimization of electric motors
4. Vibrations and noises
5. Efficient cooling design
6. Fault tolerant design
7. Advanced control for motor drives
