Modulator Optimization For Reduced Torque Ripple In Magnetic Gears

A magnetic gear is a machine uses permanent magnets to transmit torque among an input and output shaft without using any kind of mechanical interaction.Magnetic gears can succeed efficiencies greater than 99%at the time of applying full load and with having much higher half load efficiencies than a mechanical gearing system.Because Of higher power torque ratings,a magnetic gear will be smaller in size,lighter in weight and lower cost than a usual mechanical gear.Reliant on the space available a magnetic gear might be the only viable advantageous technology.Since there is no mechanical contact between the moving parts there is no wear and lubrication is not required.Magnetic gears inherently protect against overloads by smoothly slipping applied overload torque automatically and safely?A magnetic gear is made up of two rings of permanent magnets with a ring of flux-modulator in among,this modulator act as flux-path from each of the rings of magnets.This has the effect of creating harmonics in the fields produced by each ring of PM magnets.So,the proposed study of Modulator Optimization for Reduced Torque Ripple in Magnetic Gears investigates various flux-modulator block shapes and that analysis method compares the ripple torque characteristics of concentric coaxial magnetic gear by using an(FEA)nonlinear finite element analysis based on a 2-D numerical analysis system.However,the ripple efficiency of a coaxial magnetic gear is different based on the shape of compared flux-modulator shapes,to get a good result of meshing,Results are observed at various mesh operations,in this thesis the range of ripple Torque Performance Comparison in Coaxial Magnetic Gears with Different Flux-Modulator Shapes is reported.The results of an ANSYS Maxwell analysis are compared with different torque values obtained from the simulation,with specifically designed different flux-modulator shapes improvement for solving and reviewing the Ripple Torque problems.The Designs are models up of a Magnetic Gear consisting of eight different modulator shapes.Which parts composed of an inner rotor,outer rotor,and flux-modulators the inner rotor in the coaxial magnetic gear designed in the present study has 4 poles,whereas the designed outer rotor has 24 poles to be the same as our initial model,which made us get smooth and better outputs from the compared gears.Since Different valuable simulation works and reliable way of collecting data analysis system,I applied at thus modulators of compared magnetic gear.Therefore,the results obtained from the simulations are reliable and the comparison process is also acceptable.
