Abstract: Considering the influence of the mutual inductance between two windings,the mathematic model of redundancy BLDCM was established first in this dissertation.According to the main parameters of the motor,established the model of redundancy BLDCM in Magnet then.The static simulation show that the magnetic circuit design of the redundancy BLDCM is reasonable.The dynamic simulation show that the redundancy BLDCM has fast dynamic response and great capacity to load.
