The structure and principle of this machine is introduced, and the electromagnetic design method is presented in this paper . In additional, the structure of the motor size is optimized by 3-D finite element method. A prototype is designed and manufactured. The no-load back-EMF and static thrust experiments are carried out . The theoretical analyses agree with the experiment results well. That verifies the validity of the theoretical analysis as well as the rationality of motor design .
