What is a Brushless DC Motor with Integrated Commutation

Older copper brushes caused more wear to the commutator, causing deep grooving and notching of the surface over time. By contrast to direct current motors, DC motors are very ruggedly designed especially when it comes to brush wear. To get maximum life out of your brushes and maintain good DC commutation, A direct current motor, into which a plane conductive pattern is formed and including a commutator section including a wear of the contact electrode
