Shafts are a component of an armature assembly or a rotor assembly in an electrical rotating machine. The shaft's purpose is to transmit mechanical power into or from an electrical rotating machine. Shafts are designed and manufactured to high tolerances for a specific electrical rotating machine. Worn, damaged, or otherwise non-conforming shafts can be removed from armature and rotor assemblies and replaced with new shafts. The special process of shaft replacement ensures accurate positioning and exact alignment of new shafts.

Sherwood Electromotion Inc. (SEI) supplies new shafts and provides comprehensive shaft replacement services. SEI supports all types of shafts used in various electrical rotating machines.
