Electric motors run maintenance-free most of the time; many are self-lubricating and only occasionally require the oil wells to be topped up. Many of the parts in an electric motor are effectively non-serviceable as a do-it-yourself task, such as the windings, but you can replace the brushes that make contact with the armature.
