Energy saving in electric drives of pilgering mills

The key ways of energy saving in the electric drives of pilgering mills are considered: improvement of the kinematic chain, the main components of the losses and ways of their reduction in the electric drives with DC and AC motors, electric drive energy saving control laws. It is shown that the maximum electrical losses are experienced in armature windings. The article pays attention to the high energy efficiency of parallel control circuits of the excitation and the armature throughout the range of the torque changed in the electric drive of the pilgering mills with uneven load.
