Study on Belt Conveyor Direct Driven by External-Rotor PMSM

Article Preview

Abstract:

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 external-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.
