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
