#183409 - A DC Tacho Responding to: ???'s previous message |
yes,I'm sure this tacho generate dc voltage proportional to shaft velocity,because with constant dc voltage applied to motor,there is not any pulses coupled to dc output,
I have used ad7716 a 22bit sigma delta adc to capture tacho signal, it seems after applying a simple rc filter,only 6 bit fluctuates,and it is good for my purpose, Thanks Per for your time and knowledge sharing. |
