In the application process of 220 polyimide  electromagnetic wire, due to various reasons, its temperature will slowly rise and then become hot. If no cooling measures are taken in time, the polyimide magnet wire may be burned. Therefore, find out the reason when the 220 electromagnetic wire heats up, and then try to reduce the temperature to avoid the electromagnetic wire being burned.
Let's briefly talk about some reasons and solutions to make the electromagnetic coil heat.
If it is a DC electromagnet, to reduce the temperature of the energizing coil needs to convert the energy it consumes in the resistor into heat, and reduce the temperature in the wire.

In the case of an AC electromagnet, its coil temperature rise is due to the temperature rise of the iron core in addition to its own resistance. If there is induced current in the iron core in the AC magnetic field, part of the electrical energy will be lost, and the temperature of the iron core will rise accordingly. The electromagnetic oven uses this principle to increase the temperature. Since the coil is wound on the core, the temperature of the core will decrease after the heat is transferred to the coil. In order to amplify the induced current loss in the core, the AC electromagnet is similar to the transformer. It is best to use mutual components. The silicon steel sheet that plays the role of insulation is used as the iron core, and its loss is amplified, and the temperature of the coil can be reduced.

However, if the electromagnet is always energized and its temperature only rises to about forty degrees, this phenomenon is normal, so don’t worry.
