Abstract
A drum-type shearer loader for the extraction of mineral material in the mining sector, has 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 an end of the support arm (2), in the region of a support arm head (3). A compact drive unit for all operating states is provided with the drive motor (4) in the form of 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).
Claims20
A drum shearer loader for extracting mineral material in mining, the shearer loader comprising:
- a pivotable support arm;
- at least one shearer drum is mounted rotatably in the pivotable support arm, at a support arm end;
- a driving motor arranged at the support arm end in an area of a support arm head, wherein the driving motor is configured as a permanent magnet-excited synchronous machine, which provides a total driving power needed for rotation of the shearer drum during operation of the shearer drum.
A shearer drum, which is mounted rotatably at a support arm head of a pivotable support arm of a drum shearer loader for a selective extraction of minerals, the shearer drum comprising:
- a driving motor arranged at the support arm head of the pivotable support arm and is in functional connection with the shearer drum via means for torque transmission, wherein the driving motor is configured as a permanent magnet-excited synchronous motor, which provides a total driving power necessary for rotating the shearer drum during the operation of the shearer drum.
