The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Using variable-speed drives can save significant amounts of energy. These drives utilise motors and power electronics to operate the system at the highest efficiency. However, the high cost of such drives is the most important issue restricting their wider application. Although the cost of power electronics has dropped substantially in recent years, the motor cost has been relatively unchanged. To address this issue, we propose an innovative motor construction method using soft magnetic composites materials, which is simpler and provides higher assembly tolerances. The method will reduce the motor manufacturing cost and improve its efficiency and so make the use of variable speed drives more attractive in many other drive applications.Read moreRead less
