Question

what is the function of commutator?

Answer 1

hope it helps you

Function of commutator: To keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the current at that point.

Answer 2

The functions of Commutator:

• The commutator or a ‘slip ring’ is used in DC motor.  

• The DC motor is used to prevent the change in torque when the blade of the DC motor is right angle to the perpendicular plate of the motor.  

• When the blade is at right angle, then the commutator reverses they ‘Direction of the current’.  

• Hence as the direction of the current is reversed, the torque is changed in the direction.  

• As a result due to a dipole formation the blade moves completely in 360 degree.
