Realizing method of magnetization curve on dc electromotor 直流電動機磁化曲線的實現方法
Compared with traditional electromagnet , this device has many merits . the article discusses methods of magnetization and demagnetization by the pulse of strong current . then the problems about whirlpool and material ' s selecting are discussed 介紹了永磁起重吸盤的工作原理及相對于傳統電磁鐵的節能、省材、廉價、安全等特點,討論了應用電容儲能經rlc串聯二階電路放電產生的強電流脈沖對永磁體進行充、退磁的方法及渦流問題。
By now , the main measure methods of magnetization characteristic are epstein frame method and ring specimen method , while the measure theory and measure method of epstein frame method and ring specimen method have drawback , they ca n ' t meet the demand of high accuracy 到目前磁化特性的測量方法主要是愛波斯坦方圈法和環形樣件法,但不論是愛波斯坦方圈法還是環形樣件法,其測量原理和測量方法都有缺陷,不能滿足高精度測量的要求。
