摘要:電動機的弱磁控制是起重設備的一個重要核心功能。起重設備根據載荷的重量自動調節起升機構的最大運行速度,既能提高起重設備的運行效率,增加經濟效益,也能減少電動機以及變頻器的額定功率,最大限度地降低功耗。弱磁參數的測定是一個復雜的過程,本文將介紹一種相對簡單,特別是在改造過程和后期修正參數的一種簡單方法。
關鍵詞:弱磁計算;簡易弱磁參數測量;弱磁理論計算與工程估算
Abstract: Field weakening control of motor is an important core function of crane. According to the weight of the load, the crane hoist axis can automatically calculate the maximum lifting speed of the lifting mechanism, which can not only improve the operation efficiency, increase the economic benefits, but also reduce the rated power of the motor and frequency converter, and minimize the power consumption. The measurement of field weakening parameters is a complex process. This paper introduces a relatively simple method, especially in the transformation process and later correction of parameters.
Key words: Field weakening calculation; Simple parameter measurement; Field weakening theoretical calculation and engineering estimation
