The Carnot engine is the best example of a cyclic process. An example of such a system is a refrigerator or air conditioner. If the cycle goes anticlockwise, then the work is done on the system every cycle. If the cycle goes clockwise, the system does work. As well as to restore the motor rotation to the forward. The net work involved in a cyclic process is the area enclosed in a P-V diagram.

So that the motor can rotate to the left (reverse). The angles set on the reciprocating motor are specific to the Reciproc blue instruments. The end result, related to the forward and reverse rotations, is an advancement of the instrument in the canal. NC auxiliary contacts here serves as a safety interlock.įor example, if on1 pressed and K1 active (motor rotates forward), although ON2 pressed the electric current will not flow to the coil K2, because NC (K1) has been opened.Īnd for reverse rotation (reverse), then the OFF button must be pressed in advance, so that K1 off and ON2 button can now be pressed to activate the coil K2. When it rotates in the opposite direction, the reverse rotation (smaller than the forward rotation) the instrument will be immediately disengaged. K1 active when it means the motor rotates to the right (forward).įrom the picture above also seen the NC auxiliary contact (K1) which is mounted in series with the coil K2, and vice versa NC auxiliary contact (K2) mounted series coil K1 premises. So that the electric current flowing through the contactor coil to NO auxiliary contact (K1) is. In the picture above shows that the electric current will flow and activate K1 if on1 button is pressed.Īlthough on1 released K1 will remain active, this is because there interlock of NO auxiliary contact (K1) which is mounted parallel to on1. This voltage depends on the actual granting of the coil can also kontaktornya because the coil working voltage of 100V, 200V and so on. So that the picture above to get the power supply phase (R) and zero (N).īut usually also used the contactor coil 380VAC working, so it should be given the power supply voltage line (phases). Working voltage contactor coil control circuit in the picture above is 220VAC.
