| 摘要 |
The invention relates to a sensor for angles of rotation, having several scanning elements on a first part positioned at the following angles of rotation 0 DEG (B), 45 DEG (A1), 135 DEG (A2), 270 DEG (C) and a ring-shaped closed code track on a second part, which is subdivided into two areas (20, 22), each corresponding to 180 DEG . The outputs of the scanning elements positioned at a rotational angle of 45 DEG (A1) and 135 DEG (A2) are connected to each other by means of an "Exclusive or" logic gate. The output of said gate forms a three bit signal in conjunction with the outputs of the scanning elements positioned at a rotational angle of 0 DEG (B) and 270 DEG (C). Each value of said signal corresponds to 8 rotational angle areas, each covering 45 DEG . |
