Study on Belt Conveyor Direct Driven by External-Rotor PMSM

摘要

As material transmission equipment,belt conveyor is widely used in coal,electricity,machinery and other industries.This paper proposes a belt conveyor that directly driven by external-rotor PMSM,the drive-roller is the external-rotor,remove coupling,reducer and hydraulic coupling.The new drive system features low power consumption,high efficiency,minimum in size and weight,stable and noiseless action.Ensure the same transportation capacity,taking the SSJ1000/2×75 belt conveyors as object design a 100kW extemal-rotor PMSM direct drive belt conveyor.The analysis result shows the new PMSM direct drive belt conveyor is feasible; at last,design a water cooling system for the fever problem of the new belt conveyor.
