Drum-type shearer loader, and shearer drum of drum-type shearer loader

In the case of a drum-type shearer loader for the extraction of mineral material in the mining sector, having at least one shearer drum (1) which is mounted rotatably on a pivotable support arm (2) and which is driven by a drive motor (4) arranged at the same end of the support arm (2) in the region of the support arm head (3), a compact drive unit for all operating states can be provided if the drive motor (4) is designed as a permanent-magnet-excited synchronous machine which, during operation of the shearer drum (1), provides the entire drive power required for rotating the shearer drum (1). 在矿业中用于获取矿物材料的滚筒式采矿装载机中，所述滚筒式采矿装载机具有至少一个采矿滚筒(1)，所述采矿滚筒可转动地支承在可枢转的支臂(2)上，所述采矿滚筒由在支臂头部(3)的区域中设置在支臂(2)的相同端部上的驱动马达(4)驱动，如果所述同步马达(4)实施为永磁激励的同步电机，所述同步电机在所述采矿滚筒(1)运行期间提供用于使所述采矿滚筒(1)转动所需的总驱动功率，那么能够提供用于所有运行状态的紧凑的驱动单元。
