Purpose of brushes and commutator in dc motor
WebThe brushes are connected to the commutator bars which allows the current to flow into the winding. What is the purpose of a brush in a motor? A brush or carbon brush is an electrical contact which conducts current between stationary wires and moving parts , most commonly in a rotating shaft. WebBrushed DC Motor. The magnetic field in a brush DC motor is produced by current sent through a commutator and brush that are connected to the rotor. Brushes are made of carbon and can be separately excited or self excited. The stator is the enclosure that contains the components of the motor and contains the magnetic field.
