Commutator in DC Generator. The commutator in case of a DC generator, the induced e.m.f within the armature coil will change in nature. Consequently, the flow of current in the armature coil will also be changed. This current will be reversed by the commutator at the exact time while the armatures coil crosses the magnetic unbiased axis Sparking brushes wear faster and can burn the edges of the commutator bars. Coil Current Reversal. Figure 1(a) shows a coil X about to undergo commutation. The DC generator is shown as supplying a current of 2I a amperes to the load, half of which is passing through this coil and the other half passing through the other side of the armature In order to tap into all this electricity the generator produces there are brushes that contact the commutator. The commutator is made up of the copper bars that are soldered to the conductors or coils of wire wrapped around the armature.

Here, to run a dc machine either in the case of motor or generator it is essential to have current to be alternating which is done through process commutation by the commutator Commutators and brushes are used on all DC generators and DC motors. They are also used on some AC motors such as the repulsion, synchronous, and universal motors. All generators produce a sine wave, or AC currents when the rotor turns in the magnetic field. The commutator on the DC generator converts the AC into pulsating DC A commutator is a rotary electrical switch that periodically reverses the current between the rotor and the external circuit. The commutator was discovered by William Ritchie and Hippolyte Pixii in 1832. Commutators are used in DC machines ( DC motors and DC generators) universal motors.

Looking at the wear patterns on a commutator is a fairly simple way of analysing the motor performance. When a motor is operating normally, the brush current will vaporise some of the copper molecules and deposit them as a copper oxide film on the commutator, this film is usually uniform tan to charcoal brown in colour Step 1: Prep. Clean the commutator using a toothbrush and contact cleaner. Spray the contact cleaner on the commutator, then agitate the surface with the toothbrush. This will remove any oils, dust, dirt, or any other contaminant which can cause connection issues and prevent any contaminants from traveling when we clean up the copper surface in.

Commutators: Basics on AC and DC Generation - YouTub

Commutator - The commutator is cylindrical in shape. Several wedge-shaped, hard drawn copper segments form a commutator. The functions of a commutator: To connect stationary external circuits to the rotating armature conductors through brushes and. To convert induced alternating current into direct current. Working Principle of DC Generator DC Generator Action. Simple direct current (DC) generators contain an armature (or rotor), a commutator, brushes, and a field winding.The interactive tutorial presented below examines the operation of a simple DC or direct current generator The action of the commutator allows the generator to produce a DC output. By replacing the slip rings of the basic AC generator with two half cylinders (the commutator), a basic DC generator is obtained. In Figure 3, the red side of the coil is connected to the red segment and the amber side of the coil to the amber segment.. Commutator and Brushes on DC Motor. 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.The electrical contacts to the rotating ring are called brushes since copper brush contacts were used in early motors Commutator Machine. an electric machine, such as a generator or motor, in which the rotor winding is connected to a commutator. A distinction is made between DC and AC machines. DC commutator machines are widely used, but the presence of a commutator limits their power to several megawatts and their voltage to 1.5 kilovolts

The function of commutator ring in an electric motor is to reverse the direction of current flowing through the coil every time coil just passes the vertical position during a revolution. Hence as the direction of the current is reversed, the torque is changed in the direction. Commutators and brushes are used on all DC generators and DC motors The commutator is a mechanical rectifier which converts the alternating emf generator in the armature winding into direct voltage across the brushes. The ends of the armature coil or winding are connected to commutator segments Shut down the prime mover on the reversed generator.
