ELECTROMAGNETIC INDUCTION HEATING DEVICE

摘要

An electromagnetic induction heating device comprises a pair of spaced-apart cores. Each of the cores has three arms with a coil wound about each of the arms. In each of the cores the coil wound about one of the arms is reverse wound compared to the coils wound about the other two arms. A controller controls the flow of current to the cores to generate magnetic fields at the arms of the cores. A workspace between the cores receives a workpiece to be heated. Preferably the cores are connected to a three phase alternating current supply.
