Dynamic braking of asynchronous motor drive of belt conveyor for load minimization in transient conditions

The goal of the research is enhancement of belt conveyor efficiency and reduction of conveyance and power cost in the mining industry. The main research tool is the developed mathematical model of a conveyor, which allows analyzing transient behavior of asynchronous motor drives of the conveyor transport. The subject of the research are the braking conditions of asynchronous motor drives of belt conveyors. The research uses the methods of modern theory of electrical machinery, theory of control and mathematical modeling. The application of the dynamic braking of the conveyor drives is discussed. Dynamic braking essentially curtails the drive deceleration time when the conveyor belt slip is possible on the drive drum, and can also diminish heat loss. The automatic tensioner can ensure pulling ability of drives. The research result is the developed mathematical model of the dynamic braking of asynchronous motor drives for belt conveyors in mines with regard to coefficient of resistance of belt and rollers.
