Abstract
THE FIRST ELECTRIC shovels were equipped with rheostatic control with both d-c and a-c motors and date back to 1902. A shovel presents a variety of problems to tax the ingenuity of the motor and control application engineers. For example, a shovel hoist adds to the usual mine hoist problems, the requirement of stalling under load without interrupting motor torque.
