Hello everybody, I am basically in computer & electronics field. In one of my project, I want to get the status of the motor of cnc machines (to detect whether it is running or not). Speed is not important. Presently I am using proximity sensor near the motor shaft. I get pulses when motor is running. Then I have to convert these pulses to a continuous signal. I am looking for some simple mechanical arrangement to detect linear or rotary motion. So that a limit switch will operate when motor is running. Thanks.
