The formation of this starter has been shown in the figure. We have seen that DC motors can not be combined with direct supply because the motor is damaged. To avoid this, the starter is used. We use the DC stator And we will now know about the DC4 point starter                                Its composition has been shown as shown in the figure. We can see that one end of the DC solution is given in overloaded relay, and given in the handle. It is arranged in accordance with the order of the motor of the motor through Resistance. .and the other end of the DC clearway is given directly to the other terminal of the motor, ie, the starter is attached to the motor series. The nvc coil is also found in the stator Holds the handle on the motor coming to the fullspeed                      Now when the collapse of the current supply falls, the magnetis...

                                 It can also be called a three point starter. Its structure is shown in Figure. To start the motor, the handle is moved from off position to the first contact position. The total obstacle is in the armature circuit, the field connection is connected directly to the supply through a volt coil. Comes in as soon as the speed of the motor increases in the same way as the archete back emf emits and decreases in the value of current Now the handle is moved to the second step. Again this type of function will be done eventually at the last step of the handle. This time the armature will connect directly to the supply and this time the handle does not come with a no-volt coil. The magnet will hold the handle in the walt coil, and the motor will not need to hold the handle to continue and the motor will rotate in full speed.               ...
