An Improved Method for Calculating the Power Consumption of Electromagnet Coil

Abstract

The electromagnet coil is an important electromagnetic conversion element, which has been used in many fields. However, due to the existence of resistance, a significant amount of energy is lost as heat, resulting in waste. So, it is necessary to study the power consumption characteristics of electromagnet coil. In order to solve the above problem, an improved calculation method of power consumption is proposed in this paper. Firstly, the power consumption model of electromagnet coil is deduced, and the influence weights of the nominal diameter, paint layer thickness and stretch ratio are analyzed by sensitivity. Secondly, an FEM finite element method simulation model and test platform of electromagnet coil are established, which are used to simulate and test the power consumption in different structures and temperatures. Finally, the results of calculation, simulation and experiment are compared. The results show that the appropriate structural parameters can effectively reduce the power consumption of electromagnet coil. Furthermore, the influence of different parameters on the power consumption is different. The relevant results can provide a theoretical basis for the design of electromagnet coil, which has a certain engineering value.
