  • Belt-conveying installation, method for operating the same, and use thereof
    Patent number: 9573765
    Abstract: A belt-conveying installation has at least one carrying structure, a conveying belt and at least one drive apparatus for driving the conveying belt. The drive apparatus includes at least one drive shaft, at least one drive-shaft-bearing arrangement, at least one drive roller and at least one independently excited drive motor in the form of a frequency-converter-fed alternating-current synchronous motor with a stator and a rotor. The drive shaft and the at least one drive motor are connected to one another without any gearing, and the rotor and drive shaft are arranged coaxially, each drive shaft being guided through at least one rotor. The belt-conveying installation can be operated and used for heavy industry, in particular for the extractive or mining industry.
