Abstract
This paper deals with a noise and vibration of brushless dc (BLDC) motors due to the asymmetrical overhang of permanent magnet. The asymmetrical overhang of permanent magnet is generating z-axis thrust which is lead to eccentric force and vibration of BLDC motor. The z-axis thrust considering asymmetrical overhang effect of permanent magnet is analyzed by using 3-D FEM and the result is compared to experimentation.
