| 摘要 |
The invention relates to a gearless rotary encoder, comprising at least one encoding disk (20) connected to an encoder shaft, a light source (22), a single-turn light sensor unit (25), a multi-turn light sensor unit (25), an evaluation unit (41, 42) for evaluating the signals of the single-turn and multi-turn light sensor units, and an energy storage unit comprising a switching unit, an oscillator (64) for the clocked control of the switching unit, and an energy storage (24), wherein the switching unit is designed to connect the evaluation unit, the light source, and the multi-turn light sensor unit to the energy storage for a self-contained power supply. The rotary encoder is characterized in that a logistics unit (44; 43, 45, 46) is provided, to which the signals of the multi-turn light sensor unit are supplied for evaluation and which is designed to control the switching unit when a valid signal of the multi-turn light sensor unit is present in order to interrupt the self-contained power supply. |
