Abstract: In this paper,a mechanical-electrical-thermal test system for the electromagnetic heating machines(EMHM)was firstly built,which was designed to test the thermal power characteristic of the EMHM by measuring its input rotation speed and torque.The temperature rise and quantity of the accessed water,and the input rotation speed and torque were all tested online,and the thermal conversion efficiency was correspondingly obtained.Secondly,a test system for the magnetization of water by the EMHM was built in order to test the variations of the physical and chemical properties,such as conductivity,pH value and ion concentration etc.,of water after flowing through the EMHM.Related tests were done on a prototype.The test results proved the feasibility of the two test systems mentioned above,which was significant to the theoretical research of EMHMs.
