Abstract
A method of fabricating a stator and a stator where the method includes providing a plurality of electromagnet cores, with each electromagnet core having a stack of laminations defining a tooth and a yoke segment. The yoke segment is defined by a stack of laminations having a tongue structure and an opposing groove structure. Representative methods also include providing an insulating bobbin surrounding a portion of the tooth of each lamination, such that each lamination is held against adjacent laminations by the bobbin. The method further includes the step of winding electrically conductive windings around a portion of the bobbin, and assembling the plurality of electromagnets into a stator by mating the tongue structure and the groove structure of each electromagnet with a corresponding tongue structure and a corresponding groove structure of adjacent electromagnets. Additional embodiments includes a stator having the above characteristics.
