This topic mainly is in the familiar threephaseasynchronous motor principle foundation, according to designs therequest to design a small threephase mouse cage type asynchronousmotor. First determined the electrical machinery the electromagismload and the electrical machinery main dimension, then separately tothe electrical machinery winding, the electrical machinery iron corecarries on the design, and to designs the electrical machinery theparameter, the operating performance carries on the calculation,repeatedly adjusts, conforms to the design duty requirement until thedesign parameter. Changed the air gap size, the change stator numberof windings in the primary election plan foundation, and the changecore length has carried on several plans designs, finally carried onthe parison to all design proposal, the optimized design. Key word Electrical machinery, electromagism design, changeparameter 攀枝花學(xué)院本科畢業(yè)設(shè)計 目錄 目 錄 摘 要 .............................................................................................................................I ABSTRACT ......................................................................................................................
