Abstract
A drive device for a working machine for heavy industry, particularly for the raw-materials and mining industry, includes a permanent-magnet-excited motor and a frequency converter, wherein the motor has a rotor and a stator, and wherein the motor is a segment motor, in the case of which the rotor and/or the stator is composed of a plurality of segments, where considerable improvement in the availability of the motor is achieved because the motor has a segmented design, whereby the reliability during operation of the drive device is also increased.
