| 摘要 |
The invention relates to a pump unit comprising a pump (4) and an electric drive motor (6), in addition to an electronic control unit (8), which has a module (14) that identifies the correct rotational direction (CW, CCW) of the drive motor (6) and the pump (4). Said module has means (22, 24) for detecting at least one output characteristic value (H, Q, P) of the pump unit and is designed in such a way that when the drive motor (6) rotates, the module detects at least one output characteristic value (H, Q, P) and determines the correct direction of rotation by evaluating the output characteristic value (H, Q, P). |
