Key Characteristics: High Strength: Armature shafts are typically made of high-strength steel to withstand the mechanical stresses of rotation.
Components and Features: Bearings: Used to support the shaft and reduce friction during rotation. Brushes: Conduct electrical current to the commutator. Commutator: A device that reverses the direction of current flow in DC motors, ensuring continuous rotation. Laminations: In DC machines, the armature core (which the shaft is part of) is often made of steel laminations to reduce eddy current losses.
