Study on Consumption Reduction Performance of Permanent Magnet Drive Technology in Coal Preparation Plant
In response to the problems of low transmission efficiency,high energy consumption,high maintenance costs,and large footprint of traditional asynchronous motors in coal preparation plants,research is conducted on the key technologies for reducing consumption performance of asynchronous motors in coal preparation plants.A permanent magnet driven asynchronous motor is developed,and a mathematical model for permanent magnet driven asynchronous motors is established.Establish a simulation model of permanent magnet asynchronous motor using finite element analysis method,set parameters for consumption reduction numerical simulation.The results show that compared with traditional motors,permanent magnet drive technology can reduce energy consumption by 81.25%.The technology was applied to an asynchronous motor in a coal preparation plant in Shanxi,saving 90 kWh of electricity per shift.The permanent magnet asynchronous motor has the advantages of high mechanical efficiency and low maintenance costs,achieving satisfactory application results.It has certain promotion value and market prospects.
