Realizing method of magnetization curve on dc electromotor 直流電動(dòng)機(jī)磁化曲線的實(shí)現(xiàn)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(duì)于傳統(tǒng)電磁鐵的節(jié)能、省材、廉價(jià)、安全等特點(diǎn),討論了應(yīng)用電容儲(chǔ)能經(jīng)rlc串聯(lián)二階電路放電產(chǎn)生的強(qiáng)電流脈沖對(duì)永磁體進(jìn)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(cè)量方法主要是愛波斯坦方圈法和環(huán)形樣件法,但不論是愛波斯坦方圈法還是環(huán)形樣件法,其測(cè)量原理和測(cè)量方法都有缺陷,不能滿足高精度測(cè)量的要求。
