Each phase winding of the open winding brushless direct current motor (BLDCM) is connected to an H-bridge inverter, and its phase voltage and phase current could be controlled independently, which has a certain fault tolerance. The mathematical equations of the openwinding BLDCM are introduced, and the MATLAB simulation model is established. The operation characteristics of the open winding BLDCM under the fault of the power components are analyzed, and the characteristics of two faulttolerant control methods, compensation and reconstruction, are discussed. Finally, the open winding BLDCM and the corresponding controller are processed, and the experimental platform is built. The operation characteristics of the open winding BLDCM under normal operation and fault tolerance compensation operation are verified.
