| titleOfInvention | Speed detection device and servo motor |
| abstract | PROBLEM TO BE SOLVED: To provide a speed detection circuit and a servomotor capable of detecting a moving speed or an angular speed with high accuracy with a small arithmetic circuit. A speed detecting device, a plurality of tentative angle Φi previously set, and a memory 52 for storing the values cos i and tan i trigonometric function for each of the provisional angles of the plurality of first A first register R11 for storing the first coordinates (x1, y1) of the moving body obtained by the sampling, and a second actual state of the moving body obtained by the second sampling next to the first sampling. A second register R21 for storing coordinates (x2, y2), and a second coordinate (xc i , yc i ) expressed by multiplication, addition or subtraction of the first coordinate and the value of the trigonometric function Is calculated so as to be close to the actual second coordinate, and the speed of the moving body is calculated based on a temporary angle corresponding to the value of the trigonometric function used for the calculated second coordinate. And. [Selection] Figure 2 |
