Control a Motor

You can use a limit or proximity switch to detect the end of desired travel, and shut off the motor. Another way is to use a current sensing relay to detect the rising torque (and hence current) of the motor. And possibly other ways.

Thank you

It help as I think the detection of the rising torque is the solution I don t know how it works but hope it uses the extra effort of the motor, is it write??

Your motor mechanism is used for the linear operation you can use limit switch or proximity sensor or you want control the torque of the motor you can use torque switches.

Thank you

You also help a lot.

Although Tornado is correct in a general sinse, in reality you have not provided us with NEARLY enough information. There are THOUSANDS of different types of "motors", a near infinite size range and the term "end" can be interpreted in a lot of different ways. For example, using a current sensing relay is totally inappropriate for a 10,000HP 12kV motor application, or a limit switch may be grossly inacurate if your total travel distance is only 3mm.These are extremes of course, but your lack of detail leaves me wondering how to help.

I build a a mechanism with a motor and I need something that stop the motor when it end the function.

what does this invention do?.. if we know what its function is, maybe we can help further!!
