Abstract:
A method of fabricating a motor stator, comprising the steps of:providing a first stator frame part;providing a second stator frame part including first and second pole portions separated by a stator bridge, wherein the stator bridge comprises a non-magnetic material, and the step of providing the second stator frame part including the first and second pole portions separated by the stator bridge comprises:providing first and second pole portions separated by at least one alignment strip;situating the stator bridge between the first and second pole portions; andremoving the at least one alignment strip so that the first and second pole portions form discrete pieces of the second stator frame part;providing two magnetic arms extending from one of the first and second stator frame parts;situating a bobbin wound with an electrically conductive coil on each of the two arms;coupling the first and second frame parts with the arms so as to leave an opening between the two bobbins and the first and second frame parts for insertion of a rotor.
