Principle and Analysis of Structure of Low-Speed High-Torque Gear Meshing Motor Driven by Radial Force

This paper proposes a new motor structure based on electromagnetic radial force drive, which converts the radial electromagnetic force into output torque through the meshing action of the gear pair, resulting in a significant increase in torque density. In this study, the flux density distribution characteristics of this motor are qualitatively analyzed and the force transmission process of the gear is described. The results of the internal gear radial force overtime were calculated using finite element analysis to demonstrate the feasibility of the structure.
