CMI researchers from Ames National Laboratory conducted the activity for this highlight
Innovation
An accurate motor designing tool is developed to determine the most suitable motor for less critical SM-Fe-N magnets. The design shows comparable (even improved) performance with Sm-Fe-N magnet against the Nd-Fe-B magnet motor.
Achievement
The matched rated performance can be obtained with Sm-Fe-N magnets with the improved efficiency.
The over all mass and volume of the motor is lower than the original Nd-Fe-B magnet motor.
Significance and impact
The identification of suitable designs for reduced/less critical RE magnet usage in PM machines is a very essential step towards the addressing the criticality and potential supply disruptions.
Hub Goal Addressed
Reduction of critical RE magnets usage in PM motors.
