High speed motors rotating at speeds above 10,000 rpm are gaining more attention nowadays for various high performance applications. High efficiency and reliability are demanded by the applications like centrifugal compressors, pumps, machine tools, drills, aerospace etc. This paper presents novel design and analysis of a high speed axial flux permanent magnet motor for high speed, low power applications...
Future Pressurised Heavy Water Reactors (PHWRs) are expected to use Slightly Enriched Uranium (SEU), which can increase the nuclear burn-up by about three times compared to the current nuclear technology. High speed centrifuge rotating at speeds above 30 krpm is essential for uranium enrichment. This paper presents novel design and analysis of a high speed axial flux permanent magnet motor for centrifuge...
Optimization plays a crucial role to bring out a trade-off between the cost and efficiency of permanent magnet motors. Optimization algorithm coupled with analytical magnetic circuit analysis, is one such technique to improve the performance of a motor. However, the non-linear effects like saturation, cross-magnetization, etc. are cumbersome to be modelled analytically. In addition, the interdependency...
In this paper, conversion of existing Internal Combustion Engine (ICE) based vehicle into an electric vehicle is discussed. Such a configuration saves the investment in development of a completely new electric drivetrain. The ICE is replaced with electric drive while keeping rest of the transmission as it is. Thus, field weakening capability is not essential for the motor and surface permanent magnet...
A novel electric machine is proposed for electric vehicles (EV) to circumvent permanent magnet (PM) machine and to achieve the same performance by using the advantages of both axial flux topology and radial flux segmented switched reluctance motor (SRM). A 3-phase, 12/8 pole toroidal wound axial flux segmented SRM (AFSSRM) for EV application is proposed. Outer diameter and axial length of the motor...
