A winch for elevating at a plant, in particular for cranes, cable-operated excavators, and similar construction machinery, has a hoisting drum, an electric motor for the drive of the hoisting drum which is received in the interior of the hoisting drum, and power electronics and/or control electronics for the electric motor including at least one frequency inverter and/or frequency converter. The power electronics and/or control electronics for the electric motor are received at least partly in the interior of the hoisting drum. With the compact construction of the winch, short cabling distances are achieved, interference emissions having negative effects on electromagnetic compatibility are avoided, and voltage overshoots impairing the service life of the inverter and the motor are reduced. |
