Digitally controlled analogue angle setting device - has coding disc with number of grid strips smaller than number of stepping motor steps per revolution |
摘要 |
<p>The device sets a mechanical output shaft in an analogue angular position which can vary at most from 0 to 360 deg., otherwise within a limited arc. This is done by an electric digital input data word. An optical incremental coding disc (3) with a zero mark is rigidly connected coaxially with the rotor (1) of a stepping motor (2). The number of grid strips on the grid track of the coding disc is smaller than the number of steps of the motor per revolution. The n-stepped field cycle of the stepping motor may include the same setting angle interval as a line pair (bright/dark) on the disc.</p> |
