reverse forward starter

 Hello friends, how will we talk today that many works in our industrial and factories are completed with reverse forward

In the same way, there are many more.

We will know that many types of machines in our industrial such as grinding lifting and cranes etc., it is necessary to operate a 3 face motor in straight and opposite directions. To accomplish this type of work, a panel board is made.

We have come to know that the order of the 3 face motor is very important. If the 3 face sequence cannot work properly then the motor is moving in opposite directions to change the rotation direction of the 3 face motor for any of its two faces. The connection should be reversed and based on this the motor can be reverse forwarded.

In the same way, there are many more.

Friends, it requires two contactors and 3 push buttons, one off push button, two on push buttons and an overload relay to make it. The motor is supplied in the order l1 l2 l3 in a straight direction by the contactor k1 push button forward. There is no connection of Contractor k1, its magnetic coil remains on even after leaving the switch forward. It is necessary to turn off the motor in the opposite direction from the straight direction without turning off the nc connection of Contractor k1 does not drive the Contractor k2. Type When the motor is moving in the opposite direction, the contractor k2 nc connection does not allow the contractor k1 to run. It runs the interlocking. After turning the motor off with the push button, the push button can be driven in the opposite direction by reverse. The no connection of the contactor k2 keeps its magnetic coil on leaving the switch reverse and the face is supplied to the motor in order l2 l1 l 3In order to run in the opposite direction to Pune, it is necessary to turn the circuit off once. It is used in lift crane marble etc.

So guys you must have understood a little bit
