Abstract

This paper presents a new structure in the magnetic gearbox field, which can bring better performances rather than the conventional one. This work aims to describe a developed magnetic gear with a novelty in its physical structure which cause gearbox can experience a new magnetic field distribution. Having experienced a further distribution in its magnets plan, the new model can reveal better performances rather than the original coaxial gearboxes. Although dimensions of the new coaxial gearbox get smaller than the ones in typical design, torque transfer and fluctuating rates have incredibly improved. Simulation results, based on the proposed models, are extracted from a time-stepping finite element analysis. ANSYS Maxwell software uses the Finite Element Method in its calculations and reports the results to validate the magnetic systems operations.
