Electromagnetic Induction Heating VS Traditional Resistance Heating
(1) The Working Principle of Electromagnetic Induction Heating in Blow Molding Machines ① Electromagnetic Heater An electromagnetic heater is a device that converts electrical energy into thermal energy using the principle of electromagnetic induction. The electromagnetic heating controller rectifies 220V, 50/60Hz AC power into DC and transforms that DC into high-frequency, high-voltage electricity with a frequency of 20-40kHz. It also converts 380V, 50/60Hz three-phase AC into DC and then into high-frequency, low-voltage, high-current electricity ranging from 10-30kHz, which is used…
