ELECTRICAL SPLIT-CAGE OR CANNED COOLANT PUMP

摘要

The invention relates to an electrical canned/split-cage coolant pump (10) comprising an electric drive motor (24) and a pump module (22). The pump module (22) is driven by the electric drive motor (24). The electric drive motor (24) has a can, in particular a split cage (36). The split cage (36) delimits a wet space (42) with a delivery fluid arranged therein from a dry space (32). A permanent magnet motor rotor (28) is arranged in the wet space (42). An electronically commutated motor stator (30) is arranged in the dry space (32). A Hall sensor (64) for detecting the position of the permanent magnet motor rotor (28) is provided in the dry space (32) on the split cage (36). The Hall sensor (64) comprises a sensor head (66) and rigid electrical connection lines (62). A positioning element (60) is provided in the electrical canned coolant pump (10). This positioning element (60) has rigid electrical connection lines (72), which are rigidly connected to the corresponding rigid electrical connection lines (62) of the Hall sensor (64). In addition, the positioning element (60) has an electrically insulating connecting body (70), which holds the positioning element connection lines (72). In each case a form-fitting structure (78) is provided on the outer side of the can (36), on the one hand, and on the connecting body (70), on the other hand, by means of which form-fitting structures the connecting body (70) is fixed in a defined position on the can (36).
