摘要:
To determine the angular position of a rotating shaft starting from a standstill and going up to the highest permissible nominal speed and to suppress noise pulses in the square pulse sequence curve precisely corresponding to the tooth flank positions, a magnetic flux density signal received by a Hall cell (1) is compared with a threshold value signal (DC-TH) in a standstill output unit (2) and a standstill output signal (AS'') is produced. In addition, the magnetic flux density curve recorded by the first Hall cell (1) is compared with the magnetic flux density curve recorded by another Hall cell (1) and from that a window signal unit (5) generates a window signal (5) consisting of a sequence of pulses having a period that is approximately equal to a square pulse length. A static output signal (AS') is produced from the falling flank of the first pulse and the falling flanks of the subsequent pulses. The standstill output signal (AS''), the static output signal (AS'), the window signal (FS) and a square pulse sequence (ASR) generated in a dynamic selection circuit (3) connected to the Hall sensor unit (1) are input into an output circuit (6).
