Thanks, I have decided to use a magnet attached to the shaft along with HALL EFFECT SENSOR IC. The hall effect sensor will be better than reed switch. I have made a small circuit with 74LS123 which is retriggerable monostable multivibrator to convert the pulses into plain signal.
I have one...
Thanks, I have learned a lot from you people. All the suggested methods are really interesting. But now I realized that the mechanical methods are not possible for me to implement, so I will stop thinking over them.
Going back to my original method, I was thinking to use some sort of proximity...
Thanks everybody.
Of course the CNC machines have encoder/resolver/tacho, but as my product is to be used with different types of CNC machines, every time I will have to use different method. In some machines I get 24V signal from the servo drive. I am searching a standard method which will...
Thank you Posttygerdawg for your kind reply.
Basically I don't want to use software solution. I want to mechanically convert the rotary motion into say movement of a small lever. The lever should be on one side if shaft is rotating, & on other side when it is stopped.
I will attach a limit...
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...
