Abstract

In order to permit the removal of tachogenerator elements during maintenance services performed on the machinery, the magnet assembly of the tachogenerator is stationary, and soft iron core elements are affixed to the rotating shaft of the machinery. For servicing the machinery, the core elements may be removed without disturbing the alignment or calibration of the magnet assembly.
