    Analysis of Capacity Calibration of MPM Main Drive Variable Frequency Asynchronous Motor

    • 摘要: 連軋管生產(chǎn)所用主傳動(dòng)異步電動(dòng)機(jī)采用變頻器交流傳動(dòng),對(duì)電動(dòng)機(jī)容量設(shè)計(jì)提出了較高要求。介紹了攀鋼集團(tuán)成都鋼鐵有限責(zé)任公司Φ340mmMPM連軋管機(jī)主傳動(dòng)變頻異步電動(dòng)機(jī)的容量設(shè)計(jì)校驗(yàn)、機(jī)械特性分析情況,針對(duì)高于額定轉(zhuǎn)速運(yùn)行的負(fù)載轉(zhuǎn)矩要求,提出了新的主傳動(dòng)變頻異步電動(dòng)機(jī)的容量校驗(yàn)計(jì)算方法。

       

      Abstract: Since the main drive asynchronous motors of the MPM are of the frequency converter AC drive type,the requirement for design of the motor's capacity is rather stringent. Elaborated in the article are the capacity calibration and the mechanical characteristics of the main drive variable frequency asynchronous motor of the 14" MPM located in Pangang Group Chengdu I & S Co.,Ltd. Addressing the required on-load torque for operation with rpm higher than the rated value,a new calculation method for capacity calibration of the said motor is proposed.
