What is strips or bars of Metal insulated from each other and arranged around 1 end of an armature?

Strips or bars of metal insulated from each other and arranged around one end of an armature typically refer to a type of electrical component known as a commutator. This structure is commonly found in electric motors and generators, where it serves to reverse the direction of current flow in the windings, ensuring continuous rotation. The insulation between the metal strips prevents short circuits and allows for the proper functioning of the device.
