Numerical and experimental vibration analysis of BLDC motor

摘要

The paper considerably extends scientific knowledge concerning problems connected with vibrations of the brushless direct current motors with permanent magnets (BLDC). Comprehensive investigations have been realized both within numerical calculations and in the space of measurements. Computations were performed using finite element method using program Ansys to obtain main sources of vibration of BLDC motor. Participation of individual parts of the motor (stator, rotor) within creation of the resultant vibrations has been investigated.
