| 摘要 |
The invention relates to a centrifugal pump unit comprising at least one impeller mounted inside a pump case, a pump shaft (3) that passes through the pump housing (1), and comprising a drive (2) that adjoins the pump case (1). A drive rotor (4) equipped with permanent magnets (6) is attached to the pump shaft (3) in the vicinity of the drive (2), and external drive elements (5) transfer a turning moment to the drive rotor (4). The drive rotor (4), while serving as an identical part for external drive elements (5), is provided in the form of a permanently excited external magnet coupling half, in the form of a hysteresis coupling half containing hysteresis materials or in the form of an engine stator having a winding that generates a rotating field. |
