Optimization Design and Simulation of Frequency Conversion and Speed Control Integrated Machine

In order to realize the rapid start of equipment, the direct start method is widely used in domestic fully mechanized coal mining equipment, which forms a great starting impulse current and reduces the service life of the equipment. If a frequency converter is used to start the equipment with frequency conversion, it will face the problem of a large area and it is difficult to apply it underground. In response to this problem, the integrated variable frequency speed regulation machine studied in this paper adopts an integrated design to meet the needs of underground coal mines. The purpose of this paper is to optimize the design and simulation of the variable frequency speed control integrated machine. The experiment, which was conducted on the design of the integrated variable frequency speed regulation machine based on the optimized design, involved the experimentation and analysis of the design of the integrated variable frequency speed regulation machine for mining. Using the induction motorized structural dimension meter formula, a simulation test was conducted to compare the mining variable frequency speed regulation integrated machine with others.
