Alternating-current tachogenerator as analog scanner |
| abstract |
The invention relates to an alternating- current tachometer whose output is in linear dependence in amplitude and frequency upon the rotation rate and the recognition of direction of rotation is achieved within a very narrow error range in the region of the zero point. A multi-pole winding of meander form, arranged in the air gap in a magnetic flux circuit including magnetic yokes 1, 2 and magnet 3, on non- magnetic material 8 is energised by a magnetic flux of varying intensity. The variation of the magnetic flux is here achieved by a constantly changing maximal and minimal coupling to the winding, the slot pitch corresponding to the pole pitch. The alternating magnetic couplings are achieved by appropriate grooving on the magnetic yokes of the rotating energiser circuit in the region of the air gap, whereas the winding is stationary. The type of winding and the winding pitch or interval determines whether a single phase or a selected multi phase A.C. output is produced. The direction of rotation may be determined from the polarity of the rectified D.C. voltage. <IMAGE> |
