The simulation of brushless DC machine based on VisSim

Based on the analysis of the mathematic model of the brushless dc motor (BLDCM), a BLDCM model has been established in VisSim5.0 software. A double looped control has been adopted in the system. The validity has been testified by the simulation results and other control strategies can be applied to the system to testify their rationality. This method offers a new idea for designing the motor control system.
