Vector control of induction motor based on series iron loss;

Model of induction machines considering iron loss and effects on vector controlc;

In order to analyze the influence of inverter on the loss of submersible motor,an simulation circuit of the inverter is established by MATLAB,then the voltage spectrum of high-order harmonic produced by the inverter is given,meanwhile the copper loss and iron loss which are brought in by the submersible motor s high-order harmonic component are calculated in this paper.

Analysis and calculation of iron losses in induction motors fed by inverters;

According to the basic character of induction motor used in vehicle, this paper proposes a field oriented control model considering the iron losses.

This paper discusses the principle of harmonic effect of asynchronous motor resulting in the increase of copper loss and core loss and producing mechanical vibration,and puts forward the ways for overcoming these issues.

A new method for reducing core loss and excitation current in transfor- mers that utilizes the fundamental principles of third-harmonic flux modulation is proposed in this paper.

However, the strategy ignores core loss and results in declines of dynamic performance and efficiency.

Based on the energy consumption of the seven emphases iron and steel companies,the problem in energy consumption of ironmaking system was discussed,in addition,the energy consumption of molten iron and process energy consumption was analyzed.
