Analysis of novel rotating electromagnetic heater based on the concept of the third function of rotational motor

In this paper, the configuration and operating principle of the electromagnetic heater is presented, analytical method is applied to discuss the effects of electromagnetic and structural parameters of electromagnetic heater on the produced heating and the designing method of electromagnetic heater is discussed. On the basis of theoretical analysis, the prototype is developed and an experimental method is applied to evaluate the test. The results indicates that comparing with the methods of heating from burning, electric heating elements and static electromagnetic heating and so on, the electromagnetic heater has the merits of low cost, saving electricity, higher thermal efficiency, quick temperature rising and multiform cleanly energy such as pneumatic energy, hydraulic energy can be utilized, it is a good future from a practical point of view.
