SYSTEMS AND METHODS FOR ELECTRIC MOTOR CONSTRUCTION
摘要
Systems and methods for constructing electric motors in which a stator core includes inner and outer portions that enable slots for magnet windings to be open during construction and closed in the completed motor. One embodiment comprises a method in which an inner stator core having a plurality of slots is formed by stacking a set of laminations. The slots are open radially outward from an axis of the inner stator core and which are configured to accommodate turns of magnet wire. After the magnet wire is positioned in the open slots, an outer stator core comprising stacked laminations is positioned around the inner stator core, enclosing the slots. The inner and outer stator cores are then positioned within a housing and assembled into a downhole motor.
