Abstract (en)
[origin: EP0831236A2] The frequency transformer of the pump has a plate (22) formed as a heat sink upon which is attached at least heat generating electronic component. The plate especially lies perpendicularly to the motor's axis of rotation and is cooled by a branched off section of the supply medium. The frequency transformer (20) is attached on the end face of the motor remote from the pump and especially co-axially. A channel runs in or on the plate for the passage of cooling medium.
