Armature - ARM --

The backbone of a brushed electric motor - the coils (wire) are wrapped around the armature, and it spins in the center of the motor can. Armatures consist of the stack (laminations), motor shaft, commutator, and coils (wires). Armatures are commonly created by laminating thin slices of iron together as they are slid onto the motor shaft. Some armatures may be skewed (the 'slices' are rotated slightly as each one is stacked on the shaft) to help reduce cogging, or some armatures may have gaps (missing 'slices') to alter a motor's magnetic field or RPMs. Armatures are commonly balanced for smooth operation, usually with epoxy or by drilling.
