Description |
The paper deals with urgent for coal industry problem of designing of shearers for thin beds. The shearers should be equipped with travelling mechanisms with two frequency-controlled drives, one frequency converter, and rigid traction unit. The paper deduces from the experiments and theoretically explains a phenomenon of originating of out of phase load variations within drives of such a type. The paper gives recommendations on decrease in affect of load variations on shearer efficiency. The paper proposes a version of correcting a proportional control law in frequency- controlled drive, providing extension of a range of service speeds of the shearer as well as required moving forces.
