Abstract

An electromechanical device includes a rotor and a stator, wherein the stator includes multiple teeth excitable by a coil. The stator is formed from multiple stator sections with one section having a protrusion in spaced relation with a first tooth and a second section having a second protrusion in spaced relation with a second tooth. The protrusions have voids for receiving opposing protrusions in an overlapping manner to integrally form the first stator section with the second stator section. The electrical coil is extended around at least a portion of one tooth before mating the multiple stator sections. The rotor has a diametral magnetized magnet extending into the aperture.
