A method of simulation and modeling outer rotor permanent magnet brushless DC (ORPMBLDC) motor under dynamic conditions using finite element method by FEMM 4.2 software package is presented. In the proposed simulation, the torque developed at various positions of the rotor, under a complete cycle of excitation of the stator, is analysed. A novel method of sinusoidal excitation is proposed to enhance the overall torque development of ORPMBLDC motor.

The Moment

AbstractThe mechanical performance of permanent magnet brushless DC motor (BLDCM) servo system is affected by the moment of inertia. In order to obtain the load moment of inertia effect on the motor dynamic performance, based on the time stepping finite element method (FEM), a two-dimensional finite element model of the BLDCM is established, and the motor drive circuit is built. The motor running state under different load moment of inertia is simulated. The motor dynamic characteristics and the output performance are studied. The influence of the moment of inertia on the starting characteristics and the load sudden change characteristics is obtained. The influence mechanism of the load moment of inertia on the motor output speed and torque is revealed. Finally, a prototype platform is built to test the motor no-load EMF. The correctness of the model is verified and the correctness of the research is proved indirectly. This research is of great significance to the research of the BLDCM servo control system.
