Study of Spindle Motor Parameter Design for Improving the Performance of High-Speed Spindle Motor

[[abstract]]高速加工是一種能夠大幅提高產量及減少成本的機器，這機器能對我們的生活產生影響。主軸電機的主要製造問題高扭力與高效力。一般來說，主軸電機的效能取決於漏抗值，而漏抗值對於磁鏈從定片到轉片起到很大的作用。本文專注於兩個重點，第一:定子參數的最佳設計，來改進最大力矩、效率、定子磁鏈，以及降低額外能量的損耗和溫度的上升。第二，定子槽幾何的最佳設計，來增加效能並且減少啟動電流。使用響應面方法，Hooke-Jeeves優化，Taguchi方法和有限元分析?開發最佳設計。在本研究中，主軸電機性能估計包括擊穿轉矩，效率，磁鏈有限元分析，定子交鏈磁通和定子洩漏分析，熱設計概念，額外的功率損耗減少策略，啟動性能分析已經描述。通過使用性能估計，可以識別關鍵設計參數並且可以獲得設計結果。此外，我們製造和測試了一個原型主軸電機工業設計，以驗證最佳設計計算結果。實驗結果表明，與當前的主軸電機設計相比，最適設計產生更高的擊穿轉矩，效率，磁鏈，啟動性能，更低的溫升，額外的功率損耗和啟動電流。最適設計和原型測量結果的比較驗證了擬議模型的準確性。總體上，誤差的百分比大約為8％。[[abstract]]Highspeedmachiningisatechnologyfordrasticallyincreasingproductivityandreducingproductioncostwhichcanhaveaneffectonourlife.Themainfabricationissuesofthespindlemotorsarehightorqueandefficiency.Generally,theperformanceofthespindlemotorislargelydeterminedbythevalueoftheleakagereactance,whichhasasubstantialinfluenceonthefluxlinkagefromthestatortotherotor.Thisdissertationfocusanoptimaldesignofstatorparameterstoimprovingbreakdown(maximum)torque,efficiency,statorfluxlinkage,andreducingadditionalpowerlossandtemperatureriseofthespindlemotor,andoptimaldesignofthestatorslotgeometrytoincreasingstartingperformanceandreducingstartingcurrent.Theoptimaldesignsweredevelopusingresponsesurfacemethodology(RSM),Hooke-Jeevesoptimization,Taguchimethod,andfiniteelementmethod(FEM).Inthisstudy,aspindlemotorperformanceestimateconsistofbreakdowntorque,efficiency,fluxlinkageFEA,statorlinkagefluxandstatorleakageanalysis,thethermaldesignconcept,additionalpowerlossreductionstrategy,startingperformanceanalysishavebeendescribed.Byusingperformanceestimate,thekeydesignparametercanbeidentifiedanddesignresultscanbeobtained.Furthermore,wefabricatedandtestedaprototypespindlemotorindustrialdesigntovalidatetheoptimaldesigncalculationresults.Theexperimentalresultsindicatedthattheoptimalgenerateshigherbreakdowntorque,efficiency,fluxlinkage,startingperformances,lowertemperaturerise,additionalpowerlossandstartingcurrentthandoesthecurrentformerspindlemotordesign.Acomparisonoftheoptimaldesigncalculationsandtheprototypemeasurementresultsvalidatedtheaccuracyoftheproposedmodel.Overall,thepercentageoferrorisapproximately8%
