> Developed a prototype design ( 5kW , 100,000 rpm ) that breaks the speed limit of interior-type permanent magnet motors . It is believed to be the world ' s fastest motor of its kind .
> A proven design shows the possibility of reducing critical rare-earth materials by up to 60 % and material cost by 40 % in the motors used in compressor applications .
High-speed motors for an electrified future
Research group
The development of high-speed and fully-optimised motors is a major trend driving the transition to an electrified future . It allows electric-drive systems to achieve higher power density , more efficiency , and reduced use of critical materials . However , the mechanical and electrical stresses induced by the rotation also increase with speed and have been the major obstacle for highspeed motors .
This team has developed novel motor topologies , multiphysics modelling techniques , and genetic algorithm-based optimisation programs to push beyond the speed and performance limits of electric motors . These designs can be re-optimised to provide high powers of 100-300 kW for EV and industry servo applications . Several of the UNSW-developed motors are patented and in the early phase of full-scale commercialisation .
