Brushless motor with reduced rotor inertia

摘要

A direct current electric motor having a reduced inertia rotor includes a stator affixed to a housing wherein the stator comprises a plurality of electrically conductive windings. The stator further defines a central cavity in which is mounted a rotor. The rotor comprises a shaft, at least two magnets affixed in a radially spaced manner from the shaft, and a rotor core between the shaft and magnets that is rotationally de-coupled from the shaft and the magnets.
