Approach on Realizing Brushless Self-starting of Flameproof Three-phase Wound Rotor Induction Motor

从隔爆型绕线转子电机性能优点、结构缺陷和鼠笼电机性能局限、结构优点的两个方面出发 ,分析隔爆型绕线电机实现无刷自启动之后的独特优势。再从常规所串转子电阻特性、防爆安全性等方面 ,探讨隔爆型绕线转子三相异步电动机实现无刷自启动的方法与可能性。

In this paper, the authors analyze the unique advantage for the wound rotor motor adopted with the brushless self-starting, based on the comparison of the flameproof wound rotor motor and squirrel-cage motor in performance, structure and limitations, and listed their advantages and disadvantages. Purposely, the author studies the method and probability for adopting brushless selfstarting in the flameproof three-phase wound rotor induction motor by connecting a rotor resistance in the standard motor, in the view of the performance and explosion protection safety.
