摘　　要：为了分析新型电磁加热装置—旋转电磁致热器的设计方法,对致热器的热功率进行了研究。首先分析了致热器的热功率分布规律,提出定子热功率透入深度的概念作为致热器设计的准则,给出了透入深度随转速变化的规律,分析了透入深度在致热器设计中的作用。以此为依据,为提高致热器的热功率密度,比较了闭口槽、半开口槽和开口槽三种不同定子结构的致热器在不同转速下的热功率密度。分析了开槽结构的致热器槽深和槽宽变化对热功率密度的影响,最后对开口槽和闭口槽样机的热功率进行了测试。实验结果表明了分析的正确性。An electromagnetic heating device, is studied, in order to analyze the design method of the thermal powers of the rotational electromagnetic heater （REMH）. Firstly, the thermal power distribution of the REMH was analyzed, and then, being the design rule, the concept penetration depth of the stator eddy current thermal power was presented. Furthermore, the changes of penetration depth with speed were given, and the effect of penetration depth on the design of the REMH was analyzed. In order to increase the thermal power density of the REMH, the density of three different stator structures of closingsloted, opening-slotted and semi opening-slotted were compared at different speeds. The effect of the variation of the depth and width of the slots on thermal power density in slotted structure REMHs was analyzed. At last, the thermal powers of prototypes of opening and closing slot were tested. The result of experiment indicates the correctness of the analysis above.
