中空シャフトの磁化
Document Type and Number:
Japanese Patent JP6740473
Kind Code:
B2
Abstract:
The present invention discloses an apparatus for magnetizing a ferromagnetic, electrically conductive hollow shaft, the apparatus comprising: an electrically conductive rod-like element for generating one or a plurality of magnetic fields by means of an internal contact device arranged thereon and used for contacting with an inner contact region on an inner side of the hollow shaft; an external contact device for contacting with an outer contact region on an outer side of the hollow shaft; and a current source for generating a current pulse through the rod-like element, the internal contact device and the external contact device and also through the hollow shaft between the inner and outer contact regions; wherein a first pole of the current source is connected to or adapted to be connected to at least one current supply contact point of the rod-like element and a second pole of the current source is connected to or adapted to be connected to the external contact device, and wherein an electrical polarity of the first pole is opposite to the electrical polarity of the second pole. The invention further discloses a corresponding method.
