my question is that....few days ago i had installed a three
phase motor starter for an electric saw.the motor will run
and make the hydraulic pressure which will be goes to
pressure cylender by up and down lever.two number of
limitswitches are also installed on cylinder for safety of
motor.now when the arm of cylinder reaches to the upper or
lower limit it will cut the motor's line.and motor will be
stop.now wana know that what will i do that motor runs
continue after the limitswitch cut it down but it shold not
be made any pressure.pls answer me in brief.

Answer Posted / pvl
There should be some way to vent the excess pressure built by the motor. So first of all you should have a pressure gauge or sensor to read the pressure. Then you should have either a re-circulation line in the system or vent valve to channel the excessive pressure. When the hydraulic pressure reaches a set limit the re-circulation valve should open and channel the excessive pressure back to the tank/reservoir. In this way you can keep the motor constantly on without causing damage to system.
