Stepper motor that can stop and start at given torque
Stepper motor that can stop and start at given torque
(OP)
Hello,
I am new to this forum and I tried searching for an answer before posting here. If this is already covered I am sorry.
We need to close and open a needle valve using a motor. However, we do not want the motor to keep running when the valve has closed/opened fully at given torque. We will be using a PLC to operate this. My question is: How can I ensure that the motor stops at given torque when opening/closing.
Will be really grateful for any help and tip about this.

In static condition, the stepper motor is energized but not moving. In this way the motor shaft is held constant due to holding torque.
If your holding torque is not sufficient or if you must absolutely power-off the motor, then you could amplify it by incorporating a lead screw of some sort. Screw pitch should be high enough for no backdriving. Or simply incorporate a brake.
