Design and Analysis of Permanent Magnet Synchronous Motor for Coal Mine Scraper Conveyor
The underground working environment of mines is harsh.The conventional scraper drive system mainly em-ploys a asynchronous motor along with a reducer,and its disadvantages are high space occupation of equipment,serious heat generation,and ease of water accumulation in motor cavity.The permanent magnet synchronous motor direct driving technology is used to replace the conventional driving method,and the rated parameters are determined.The designed e-lectromagnetic scheme is then tested by a simulation carried out in a finite element software.By comparing cogging torque and overload capacity of the motor under different pole grooves,a better scheme of permanent magnet synchronous motor for scraper conveyor was finally determined.
