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 / pillay
The motor is driving a hydraulic pump.Install a relief valve
set at the correct pressure in your hyd system where the pump
can perform its task but when the piston reaches the top the
pressure build up will be too high and the excess pressure is
released through the valve, the limit switches wont be
necessary any more.the pump will be running all the time.

1- XC and the RC time constant are both measures of the reaction of C to a change in ____? 2-The power factor is a numerical ratio with a value between 0 and 1 equal to the ______________ of the phase angle. 3-When V and I are out of phase because of reactance, the product of V times I is called ______________ power 4-For _____________ inductors, the branch currents can be added algebraically. 5- The ______________ power in watts can be calculated as I^2R 6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL 2*3.141592653*1kHz*30mH =188 ohms Please check) 7-A parallel RL circuit has the values, R = 5kohms, XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
