Title: Core of brushless DC motors made of amorphous soft magnetic material
Abstract: This paper compares two prototypes of brushless dc motors (PM BLDC) with cores made of amorphous material (ASMM) and electrical sheet metal (Fe-Si). Comparative studies were performed using computer simulation in ANSYS and laboratory experiment. The results obtained confirm that the motor with an amorphous core has lower losses and a lower motor case temperature.
Key words: Brushless DC motor (PM BLDC), amorphous soft magnetic material (ASMM), Metglas, motor core, core loss.
