In this paper, a novel three phase radial driving meshing motor was introduced. The proposed motor translates the electrical energy into the mechanical energy to drive one rotor. Under the driving of electromagnetic force and restricting of the oldham coupling mechanism, the rotor was constrained to move by circle translation and drives the cycloid machine to output big torque. The control method was found, and the flux linkage characteristic was calculated through finite element method; additionally, the static torque was calculated utilizing the magnetic coenergy principle. The theory analysis is identical with the results obtained from the prototype experiments results. The prototype experiment and analysis testify the designed motor.
