Abstract: Aiming at the technology of redundancy design for motor control system, the paper presented the structure and operation principle of the redundancy high voltage brushless DC motor. The mathematical model of the motor was derived. The model of the control system of redundancy BLDCM was established in Matlab based on the mathematical model. Some simulation waveforms were presented. The experiments of the motor were made in the paper finally.The results are consistent with the simulation and show the validity of the mathematical model and simulation model. It provides a basis for further study of the control system of redundancy BLDCM.
