摘　　要：基于煤矿井下变频调速装置与电动机一体式的隔爆型变频调速三相异步电动机实现高效、节能的研发项目,根据传统的感应电动机电磁计算程序增加变频调速电动机的计算方案,并结合ANSOFT 2D有限元针对三相异步电动机的数值分析方法,进行设计核算。详细论述了变频电机的变频调速原理、控制策略,并给出实际样机,介绍其设计与制造技术。This paper describes a new product, the flame-proof variable-frequency induction motor used in coal mine. The motor is integrated with frequency converter to meet the requirement of high efficiency and energy conservation. According to the traditional electromagnetism calculation program, we add a new method for the variable-frequency motor, combine this method with ANSOFT 2D finite element to analyze and examine it, give a parti- cular description of the frequency conversion motor principle and control tactic, provide a sample motor and introduce its design and manufacture technology.
