So the commutator in contact with the armature also rotates. In this instance the effect is to get a pole reversal synchronous with the revolution of the motor - the alternating field is what they call commutated - and thus it causes the po Continue Reading 33 This helps the coil continue to rotate in a clockwise direction. The combination of the split ring and brushes is known as the commutator. How could the angular velocity of a three-phase motor be increased? But where I'm stuck is: How does the commutator switch the current flow at the right time? When the coil is vertical, it moves parallel to the magnetic field, producing no force. Definition of Split Ring. What is the difference between armature and commutator? Two or more stationary electrical contacts called "brushes" made of a soft conductor like carbon press against the commutator, making sliding contact with successive segments of the commutator as it rotates. Make a sketch of a two segment commutator and you will see that the current direction reverses every half turn. Therefore, even after the coil of wire rotates 180 degrees, the wire still experience the same force, therefore the coil just goes back on itself and this process continues. Split-ring commutator function in dc motor The split ring's role is to reverse the current at around that point. I also understand that if it weren't for the commutator, the rotor (coil) would reverse itself. https://goo.gl/VyXbLx to unlock the full series of GCSE Physics & Combined Science videos created by A* students for the new 9-1 OCR, AQA and Edexcel specifi.
