L. F. HAVEN, Product Engineer, Electrical, Bucyrus-Erie Company, South Milwaukee, Wis.
The desirable shovel speed-torque curves are described, along with the characteristics of the more important electrical components used to approximate these curves. A particular shovel regulator system combining these components is discussed in detail and some of the advantages and disadvantages of the system are given.
