摘　　要：新型旋转电磁热机,基于传统电机温升与损耗的反问题,将输入的能量完全转化为热能,并对流经内部的水媒质有磁化功能。对电磁热机的热功率进行分析是解析电磁热机内部综合物理场的基础。本文首先简要介绍了该电磁热机的工作原理,详细分析了热机的热功率构成,推导了基于二维时步有限元法的热机各热功率的解析算法。其次,针对一台样机进行了具体的热功率计算,给出了各转速下各类热功率的数值,并分析了其变化规律。最后,搭建了相应的实验平台,提出了两种热机热功率的测试方法,并进行了相关的实验研究。A novel rotating electromagnetic heating machine（EMHM） is presented based on the reverse problem of the temperature rise and loss in electrical machines. The input energy is completely transferred into thermal powers by it, and the water medium flowed through it is magnetized. Calculating the thermal power of EMHM is the foundation to analyze the synthetic physical field of it. Firstly, the operation principle of EMHM is introduced, and the component of its thermal power is discussed. The calculation method of the thermal powers, based on the 2D time step finite elemet method, is deduced. Secondly, thermal powers of a prototype are calculated, and the thermal power values at different speeds are presented, especially, the changes of each thermal powers are discussed. An experimental platfom was disigned to measure the thermal powers, and its measure method was also mentioned, and the experimental research was made.
