Because it contains only armature winding only. The normal operation of the motor is to rotate in forward direction.
How To Reverse Direction On A Dc Electric Motor Youtube
How to change direction of dc motor. Normally in forward direction the dc supply will be given such as f1 positive and f2 negative to change the direction the polarity should be f1 negative and f2 positive. Field terminal consist of f1 and f2. It is a special circuit which allows motor rotation in both directions. Another method is to use an h bridge to control the direction of a dc motor. How to reverse direction on a dc electric motor duration. Lensko lets go.
Now if we connect terminal a with ve supply and terminal b with ve supply or ground the current will flow from motor from a to b and motor will rotate in one direction say clockwise cw or forward direction. When a button which is connected to the pin 7 of the arduino is activated or pressed the direction of the rotation is reversed and continue to rotate in that direction until the button is pressed once again. As shown in figure there are two terminals a and b of dc motor. Forward and reverse direction of dc motor by changing the supply polarity in field winding or filed supply. Only take care that you change only the field or the rotary field. If we want to change the direction of the shaft we change the polarity only.
If you change both at the same time you dont change the direction. Hi guy today we make simple way to change rotation of a dc motor by use switch 6 pin music by ncs name. Yes you can change the direction of a dc motor by changing the field wires or by changing the armature wires.
