High Quality Stator Laminations
Stator laminations are accurately die-cut from thin, non-aging, high grade precoated silicon steel, which has been insulated on both sides to minimize core losses. The stator core is built up from these silicon steel segmental punchings and held under pressure between two endplates by through bolts that are tightly torqued and tack welded. Additionally, a set of core bars is welded to the stator core and to the endplates to insure tightness, torsional stiffness, and adequate transmission of airgap torque to the motor foundation. The result is a permanently tight and concentric core with uniform airgap. An exclusive TECO-Westinghouse punching design prevents the laminations from becoming dislodged. |
