PROBLEM TO BE SOLVED: To provide a direct current elevator control device capable of exhibiting an appropriate responsibility as well as suppressing temperature rise of a field winding. SOLUTION: A field current command value is generated to generate a stronger filed in a speed segment in which a torque command value required for lifting and lowering a car exceeds a predetermined value and reaches the peak. A filed winding of a direct current motor is energized based on the field current command value and an armature current command value required to generate the torque command value is calculated based on an actual field current value detected directly from a field circuit so that the calculated armature current command value flows through an armature. |
