Abstract: The article is devoted to development a new type of electric drive for mining belt conveyor that consists of a gearless drum-motor based on the slow-moving permanent magnet synchronous motor (PMSM) which ensures adjustment of conveyor speed depending on load. The advantages of the gearless synchronous electric drive are reviewed in comparison to a traditional asynchronous one. Further sections present the model of PMSM with special construction and capacity of 680 kW created by finite elements method in MagNet Infolytica software and the vector control system of PMSM using the field oriented control approach. The final part of the article contains simulation results. The simulation in Matlab Simulink software includes a multi-mass model of belt conveyor mechanics with a double drum-motor drive and stochastically determined load.

Key words: gearless drum-motor permanent magnet synchronous motor controlled electric drive for mining belt conveyor double drum-motor drive
