Induction heater hysteresis losses
WebInduction heating is an MQS process and often used in processing metals. Currents induced in transformer cores by the time-varying magnetic flux are an example of undesirable heating. In this context, the associated losses (which are minimized by laminating the core) are said to be due to eddy currents . Web30 mrt. 2024 · All electric motors experience rotational losses during the conversion of electrical power to mechanical power. These losses are generally categorized as magnetic losses, mechanical losses, copper losses, brush losses, or stray losses, depending on the underlying cause and mechanism.

Web6 nov. 2014 · Additionally, this method of heating is very efficient, as the heat is generated inside the workpiece, as opposed to somewhere else and then applied to the workpiece.In other words, with induction heating, … WebThe two most commonly encountered mechanisms by which heat can be generated by an induction fi eld are eddy current heating and heating due to hysteresis losses. In eddy current heating, a copper induction coil (work coil), which is connected to a high-frequency power supply, is placed in close proximity to the joint ( Fig. 11 ).
Web1 sep. 2001 · A program for calculating field incorporating model hysteresis to study a system of induction heating is also necessary. This program of resolution was developed using the finite element method in 2D. The energy transfer of induction heating is affected by the distance between the coil and the workpiece. Energy losses occur through heat conduction from workpiece to fixture, natural convection, and thermal radiation . The induction coil is usually made of copper tubing and fluid coolant.
