A stator for an electric motor has a laminated stator coreformed from a plurality of stacked laminations, and a stator winding formed from a plurality of coilswound on bobbins. The stator corehas a plurality of teethwhich extend radially and alternately spaced between and connected to circumferentially extending yokes. The yokes and the teeth are separately formed with each yokebeing a stack of yoke laminationsand each toothbeing a stack of tooth laminations. The teethare inserted through the bobbinsand arranged in a cylindrical form with each toothextending radially. Yokesare then fixed between radially outer endsof adjacent teeth to complete the radially outer portion of the stator core. Each toothhas a radial location surfacewhich contacts an inner surface of the adjacent yokes. The yokesand teethare fixed together by welding the yokesto the outer endsof the teeth

Stator for an electric motor

A servo motor, comprising a stator and a rotor disposed within the stator. The rotor has a core and magnets, covering the periphery of the core, forming a plurality of axially extending rotor poles. The rotor poles comprise a plurality of the magnets arranged axially, and the centers of adjacent magnets of a rotor pole are staggered by a mechanical angle in the circumferential direction of the rotor.
