Research on Loss and Temperature Rise of a Novel Dynamic Electromagnetic Induction Heater

摘要

A novel dynamic electromagnetic induction heater for water treatment system is introduced in this paper, and its structure and operation mechanism is given. The heater converts input mechanical energy into various forms of heat energy completely, including the hyseresis loss, eddy current loss, copper loss and so on, and the mathematical model of loss is established based on fundamental electromagnetic field theory. By the finite element analysis, the above three kinds of loss are calculated at different rotation speed, as well as each of the percentage of total loss. At last, the temperature field and heat flux distribution of heater are calculated.
