POTTING METHOD AND POTTING DEVICE FOR AN EXCITATION CIRCUIT PRESENT INSIDE A ROTOR BODY

摘要

The invention relates to a potting method and a device (100) for potting an excitation circuit that is arranged inside a rotor body. Said excitation circuit has a circuit board (102, 103) having contacts (103, 103') on the edge of said circuit board (102, 103), the contacts (103, 103') being arranged in a tolerance zone (109) around a cylindrical peripheral surface (110) that is concentric to the rotor body. The excitation circuit is located inside a potting zone (101) which is sealed in a liquid-tight manner by a toroidal elastic ring (111) in such a manner that surfaces of the contacts (103, 103') lying within the tolerance zone (109) are at the same time in contact with the toroidal elastic ring (112).
